Title: Post Synthesis Rapid Thermal Annealing and Characterization of Colloidal Nanoparticles

Abstract: This Masters thesis investigates the effects of post growth rapid thermal annealing on colloidal CdTe nanoparticles. This novel process has not previously been applied to colloidal nanoparticles. It is found that rapid thermally annealing with temperatures up to 400°C, the number of defect bonds in the semiconductor core will decrease and the zincblende structural phase will prevail. These findings are identified using Raman spectroscopy enhanced in a liquid core waveguide and corroborated using a variety of other analysis techniques. What is also important is that while the semiconductor core is changing, the optical characteristics of the material remain nominally unchanged. Additionally, a circulatory peristaltic pump system that is suitable for future in situ monitoring was developed and used to investigate the length effects of Teflon capillary tubes as a liquid core waveguide for Raman spectroscopy.
