This book was released on 2017 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Recent scientific progress has resulted in the development of sophisticated hybrid nanostructures composed of semiconductor nanocrystals (quantum dots, QDs) and metal nanoparticles (MNPs). These hybrid structures open up new possibilities for developing next generation nanoscale optoelectronic devices that combine the best attributes of each component material.The optical response of MNPs is dominated by surface plasmon resonances which create large local electromagnetic field enhancements. When coupled to surrounding semiconductor components, the enhanced local electric field results in strong absorption/emission, alteration in emission decay rates, enhancement in exciton emission and other interesting non-linear effects (multiphoton generation). Although hybrid nanostructures are poised to be utilized in a variety of applications, serious hurdles for the design of new devices still remain. These difficulties largely result from a poor understanding of how the structural components interact at the nanoscale. These synergetic interactions strongly depend on the exact composition and geometry of the structure, and therefore, a quantitative comparison between theory and experiment is often difficult to achieve. My dissertation work primarily focuses on paving a bridge between the experimental and theoretical studies and the mechanisms involved in exciton and multiexciton emission dynamics of single QDs in presence of plasmonic nanostructures by careful consideration of different parameters which significantly affect the interaction between these nanoparticles at a single particle level.

This book was released on 2014-06-01 with total page 211 pages. Available in PDF, EPUB and Kindle. Book excerpt: Metal-semiconductor hybrid nanoparticles combine materials with different physical properties in one nanostructure. Charge separation processes and potentially increased conductivity in thin film devices make them promising candidates for advanced applications in photocatalysis or (opto) electronics. The work on hand deals with the preparation of CdSe nanoparticles that later act as seeds for the defined deposition of metals and with the electrical characterisation of monolayers of the resulting hybrid structures. In context with the shape control of the semiconductor component in a hot injection synthesis, the role of halogen compounds and the influence of their molecular structure are examined. Analytically as well as theoretically supported explanations for the formation of the evolving hexagonal pyramidal shape, which is especially favourable for metal deposition, are presented. The deposition of different metals onto the obtained semiconductor components is examined and unusual instabilities of an Au shell on CdSe hybrid nanoparticles are investigated. Furthermore, the impact of deposited Pt on the electrical transport of CdSe nanopyramids is demonstrated.

Available in PDF, EPUB and Kindle. Book excerpt: Metal-semiconductor nanostructures represent an important new class of materials employed in designing advanced optoelectronic and nanophotonic devices, such as plasmonic nanolasers, plasmon-enhanced light-emitting diodes and solar cells, plasmonic emitters of single photons, and quantum devices operating in infrared and terahertz domains. The combination of surface plasmon resonances in conducting structures, providing strong concentration of an electromagnetic optical field nearby, with sharp optical resonances in semiconductors, which are highly sensitive to external electromagnetic fields, creates a platform to control light on the nanoscale. The design of the composite metal-semiconductor system imposes the consideration of both the plasmonic resonances in metal and the optical transitions in semiconductors - a key issue being their resonant interaction providing a coupling regime. In this book the reader will find descriptions of electrodynamics of conducting structures, quantum physics of semiconductor nanostructures, and guidelines for advanced engineering of metal-semiconductor composites. These constituents form together the physical basics of the metal-semiconductor plasmonics, underlying many effective practical applications. The list of covered topics also includes the review of recent results, such as the achievement of a strong coupling regime, and the preservation of non-classical statistics of photons in plasmonic cavities combined with semiconductor nanostructures.

This book was released on 2016 with total page 99 pages. Available in PDF, EPUB and Kindle. Book excerpt: My dissertation work focuses on several aspects in nanoscale materials for photocatalysis. Several nanostructured architectures were explored as detailed below. The present work demonstrates a general strategy for coupling the near field (NF) radiation of surface plasmons to long-lived optical excitations in semiconductor nanocrystals (NCs) was investigated. A unique signature of the plasmon to exciton energy transfer was observed in photoexcitation measurements that unambiguously correlate the increase in the CdSe exciton population with the excitation of plasmon modes in Au domains. That scheme for harvesting the NF radiation of metal nanoparticles presents an excellent opportunity for extracting the evanescent emission of surface plasmons. Furthermore, an experimental strategy was developed for monitoring the time-dependent monomer concentration during the hot-injection synthesis of Ag nanocrystals. The present approach employs Au nanoparticles as chemical probes of the Ag monomer build-up in the reaction flask. The precipitation of Ag on the surface of Au nanoparticles is diffusion–limited and results in a blue-shift of the plasmon resonance which is used to gauge the Ag monomer concentration, [Ag0]. In particular, it was shown that the nucleation rate is independent of the reaction temperature but is highly sensitive to the concentration of free ligands in solution. Eventually, a general strategy for the synthesis of colloidal semiconductor nanocrystals (NCs) exhibiting the size dispersion below 5% was demonstrated. That approach relies on the sequential deposition of fully saturated cationic and anionic monolayers onto small-diameter clusters, which leads to focusing of nanocrystal sizes with the increasing particle diameter. The present synthesis is amenable to different types of semiconductor nanocrystals and can potentially offer a viable alternative to traditional hot-injection strategies of the nanoparticle growth.

Book excerpt: This chapter will address the development of colloidal synthesis of hybrid metal-semiconductor nanocrystals and their application in the field of photocatalysis. Despite the plethora of examples of different-shaped metal-semiconductor nanostructures that have been reported, metal-tipped semiconductor nanorods are perhaps the most intensively studied, and their use as a photocatalyst will be the focus of the chapter. First, we will discuss different wet-chemical synthesis techniques to control the synthesis of these metal-semiconductor hybrid structures. Afterward, we will discuss their unique physicochemical properties that are a combination of semiconductor and metal properties. Finally, we will showcase several examples from the literature demonstrating the possible application of these unique hybrid structures in photocatalysis.
