Book excerpt: Time-resolved photoluminescence studies of individual heterostructures reveal internal energy transfer with a timescale of hundreds of picoseconds from lower-[n] to higher-[n] layers (high bandgap to low bandgap). These heterostructures capable of emitting multiple colors with high spectral purity are attractive platforms to explore new properties and physics in 2D materials. They also show promise for building versatile photonic devices that are easily solution-processed. The following appendices provide complementary information to the accomplished work presented in the main chapters. Specifically, Appendix A-H provide additional figures and tables to Chapters 2-9, respectively. Appendix I describes electrically driven light emission from 1D NWs and 2D nanoplates of cesium lead halide perovskites The remarkable solar performance of lead halide perovskites has been attributed to their advantageous physical properties that present many mysteries, challenges, as well as opportunities. The body of thesis here has demonstrated better control over the crystal growth and rational design of nanostructures of these fascinating materials, as well as better understanding of their complex solid-state chemistry can further enhance their applications. Moreover, the excellent properties of these single-crystal perovskite nanostructures (and their heterostructures) of diverse families of perovskite materials with different cations, anions, and dimensionality make them ideal for fundamental physical studies of carrier transport and decay mechanisms, and for enabling high performance optoelectronic applications, such as NW lasers.
