This book was released on 2011 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Transparent conducting thin films of metal oxides, doped metal oxides, and carbon nanotubes (CNTs), have been produced using various deposition techniques, including: Aerosol Assisted Chemical Vapour Deposition (AACVD), Atmospheric Pressure Chemical Vapour Deposition (APCVD), and Spray Coating. The resultant thin films were tested for their performance in a number of applications, including: Low emissivity ('Low-E') glazing, photovoltaic electrode materials, gas sensing and photocatalysis. AACVD was shown as a viable, and attractive, deposition technique for the synthesis of tin oxide, and doped tin oxide thin films, which allows for controllable doping levels, crystallinity, and surface structure. The tailoring of these physical attributes allows for enhanced performance of the functional properties of the films, whereby, a lower growth temperature produced highly transparent, highly conductive coatings with a low haze value for 'Low-E' applications, whereas, higher growth temperatures produced the high electrical conductivity, transparency, and light scattering properties required for high performance electrodes in thin film photovoltaics. In addition, a dual coating methodology was developed using both AACVD, and APCVD, to grow tin oxide thin films in a rapid timescale, but with modified surface structures showing changes to the short range waviness, kurtosis, and the surface area. Growth of carbon nanotubes, using CVD, was investigated over a range of metal catalysts, with varying Pauling electronegativity values, and over a range of temperature, methane, and hydrogen conditions. A growth mechanism has been postulated, whereby, the electronegativity of the metal catalyst, and the solubility and diffusion of the carbon through that catalyst, affects the type and properties of the carbon structure produced. To the authors knowledge, this is the first reported growth of MWCNTs using a chromium solo-metal catalyst, and the first reported growth of the unique 'carbon nanofibres' which were produced using gold and silver metal catalysts. Functionalisation of SWCNTs using a microwave reflux process was shown to yield sulphonate and sulphone modified nanotubes, which are highly soluble in water and able to undergo spray coating to produce carbon nanotube, nanonet transparent conducting thin films. The functionalisation process was shown to be reversible upon heating of the modified nanotubes. AACVD has been deemed unable to produced doped zinc oxide transparent conducting films. However, undoped zinc oxide films were produced. They displayed a high photocatalytic action in the degredation of stearic acid, and a UV light induced superhydrophilicity. The modification and deposition techniques, established throughout this work, were utilised to form transparent, hybrid, metal oxide-CNT coatings, for gas sensing. The hybrid materials displayed enhanced response times to combustible target gases, which has been attributed to the catalytic effects of the exposed carbon nanotube surfaces; and to the spillover of adsorbed oxygen from the active nanotubes to the metal oxide surface.

This book was released on 2014 with total page 126 pages. Available in PDF, EPUB and Kindle. Book excerpt: Colloidally prepared nanocrystals of transparent conducting oxide (TCO) semiconductors have emerged in the past decade as an exciting new class of plasmonic materials. In recent years, there has been tremendous progress in developing synthetic methods for the growth of these nanocrystals, basic characterization of their properties, and their successful integration into optoelectronic and electrochemical devices. However, many fundamental questions remain about the physics of localized surface plasmon resonance (LSPR) in these materials, and how their optoelectronic properties derive from their underlying structural properties. In particular, the influence of the concentration and distribution of dopant ions and compensating defects on the optoelectronic properties of TCO nanocrystals has seen little investigation. Indium tin oxide (ITO) is the most widely studied and commercially deployed TCO. Herein we investigate the role of the distribution of tin dopants on the optoelectronic properties of colloidally prepared ITO nanocrystals. Owing to a high free electron density, ITO nanocrystals display strong LSPR absorption in the near infrared. Depending on the particular organic ligands used, they are soluble in various solvents and can readily be integrated into densely packed nanocrystal films with high conductivities. Using a combination of spectroscopic techniques, modeling and simulation of the optical properties of the nanocrystals using the Drude model, and transport measurements, it is demonstrated herein that the radial distribution of tin dopants has a strong effect on the optoelectronic properties of ITO nanocrystals. ITO nanocrystals were synthesized in both surface-segregated and uniformly distributed dopant profiles. Temperature dependent measurements of optical absorbance were first combined with Drude modeling to extract the internal electrical properties of the ITO nanocrystals, demonstrating that they are well-behaved degenerately doped semiconductors displaying finite conductivity at low temperature and room temperature conductivity reduced by one order of magnitude from that of high-quality thin film ITO. Synchrotron based x-ray photoelectron spectroscopy (XPS) was then employed to perform detailed depth profiling of the elemental composition of ITO nanocrystals, confirming the degree of dopant surface-segregation. Based on free carrier concentrations extracted from Drude fitting of LSPR absorbance, an inverse correlation was found between surface segregation of tin and overall dopant activation. Furthermore, radial distribution of dopants was found to significantly affect the lineshape and quality factor of the LSPR absorbance. ITO nanocrystals with highly surface segregated dopants displayed symmetric LSPRs with high quality factors, while uniformly doped ITO nanocrystals displayed asymmetric LSPRs with reduced quality factors. These effects are attributed to damping of the plasmon by Coulombic scattering off ionized dopant impurities. Finally, the distribution of dopants is also found to influence the conductivity of ITO nanocrystal films. Films made from nanocrystals with a high degree of surface segregation demonstrated one order of magnitude higher conductivity than those based on uniformly doped crystals. However, no evidence was found for differences in the surface electronic structure from one type of crystal to the other based on XPS and the exact mechanism for this difference is still not understood. Several future studies to further illuminate the influence of dopant distribution on ITO nanocrystals are suggested. Using synchrotron radiation, detailed photoelectron spectroscopy on clean ITO nanocrystal surfaces, single-nanoparticle optical measurements, and hard x-ray structural studies will all be instructive in elucidating the interaction between oscillating free electrons and defect scattering centers when a plasmon is excited. In addition, measurements of temperature and surface treatment-dependent conductivity with carefully controlled atmosphere and surface chemistry will be needed in order to better understand the transport properties of ITO nanocrystal films. Each of these studies will enable better fundamental knowledge of the plasmonic properties of nanostructures and improve the development of nanocrystal based plasmonic devices.

Book Synopsis A Colloidal Nanoparticle Form of Indium Tin Oxide by : Richard Allen Gilstrap (Jr)
Download or read book A Colloidal Nanoparticle Form of Indium Tin Oxide written by Richard Allen Gilstrap (Jr) and published by . This book was released on 2009 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: A logical progression from the maturing field of colloidal semiconductor quantum dots to the emerging subclass of impurity-doped colloidal semiconductor nanoparticles is underway. To this end, the present work describes the formation and analysis of a new form of Tin-doped Indium Oxide (ITO). The form is that of a colloidal dispersion comprised of pure-phase, 4-6 nanometer ITO particles possessing an essentially single crystalline character. This system forms a non-agglomerated, optically clear solution in a variety of non-polar solvents and can remain in this state, at room temperature, for months and potentially, years. ITO is the most widely used member of the exotic materials family known as Transparent Conductive Oxides (TCOs) and is the primary enabling material behind a wide variety of opto-electronic device technologies. Material synthesis was achieved by initiating a series of interrelated nucleophilic substitution reactions that provided sufficient intensity to promote doping efficiencies greater than 90% for a wide range of tin concentrations. The optical clarity of this colloidal system allowed the intrinsic properties of single crystalline ITO particles to be evaluated prior to their use in thin-films or composite structures. Monitoring the temporal progression of n-type degeneracy by its effects on the optical properties of colloidal dispersions shed light on the fundamental issues of particle formation, band filling (Burstein-Moss) dynamics, and the very origin of n-type degeneracy in ITO. Central to these studies was the issue of excess electron character. The two limiting cases of entirely free and entirely confined electron motion were evaluated by application of bulk-like band dispersion analysis and the effective mass approximation, respectively. This provided a means to estimate the number of excess conduction band electrons present within an individual particle boundary. The ability to control and optimize the level of n-type degeneracy within the colloidal ITO nanoparticle form by compositional variation was also demonstrated. A key to the widespread adoption of a new material by industry is an ability to produce multi-gram and perhaps, kilogram quantities with no significant sacrifice in quality. Accordingly, a modified synthesis process was developed to allow for the mass production of high-quality colloidal ITO nanocrystals.
