Lamont, Ph.D. University of Pittsburgh, 2016 This thesis discusses research focused on the analysis and characterization of nanoscale systems. These studies are organized into three sections based on the research topic and methodology: Part I describes research using scanning probe microscopy, Part II describes research using photonic crystals and Part III describes research using spectroscopy. A brief description of the studies contained in each part follows. Part I discusses our work using scanning probe microscopy. In Chapter 3, we present our work using apertureless scanning near-field optical microscopy to study the optical properties of an isolated subwavelength slit in a gold film, while in chapter 4 atomic force microscopy and a three point bending model are used to explore the mechanical properties of individual multiwall boron nitride nanotubes. Part II includes our studies of photonic crystals. In Chapter 6 we discuss the fabrication and characterization of a photonic crystal material that utilizes electrostatic colloidal crystal array self assembly to form a highly ordered, non closed packed template; and in Chapter 7 we discuss the fabrication and characterization of a novel, simple and efficient approach to rapidly fabricate large-area 2D particle arrays on water surfaces. Finally, in Part III we present our spectroscopic studies. In Chapter 9 we use fluorescence quenching and fluorescence lifetime measurements to study electron transfer in aggregates of cadmium selenide and cadmium telluride nanoparticles assemblies. Chapter 10 features our work using the electronic structure of zinc sulfide semiconductor nanoparticles to sensitize the luminescence of Tb3+ and Eu3+ lanthanide cations, and Chapter 11 presents our recent work studying photo-induced electron transfer between donor and acceptor moieties attached to a cleft-forming bridge.
