Abstract
(type = abstract)
The dissertation consists of two sections, each of which addresses the excited state dynamics, charge separation and recombination in two classes of nano-structured materials. While the materials are different, the underlying theoretical background, as well as the experimental techniques which were employed in the course of these investigations is closely related. Project 1: A series of crystalline nanometer size polyoxotitanate cluster offers a good opportunity to study the structure-dynamics correlations. Its core-ligand interface, the presence of non-equivalent metal sites and quantum size supply us attractive, experimentally and theoretically tractable models to study exciton dynamics and charge carrier localization. The charge-transfer (CT), exciton dynamics and electronic structure of Ti/O clusters were studied by comprehensive approaches including ultrafast time-dependent spectroscopy, fast pulse radiolysis, ground state spectroscopy and theoretical calculations. The factors which can influence exciton dynamics are discussed individually, e.g., cluster size, surface modification, and solvent polarity. Through dynamics study of exciton in Ti/O cluster we have better understanding about the reactions occurring on the TiO2 nanoparticles, which serve as a potent photocatalyst for hydrogen production and pollutant remediation. Project 2: Surface enhanced fluorescence (SEF) of P3HT was measured in a tailored environment from silver surface with and without gold nanocones on it, and rough gold surface (Klarite substrate). The accelerated fluorescence dynamics and emission spectra were recorded through Kerr-gated ultrafast fluorescence microscope with 100 fs resolution. Competitive radiative, electron transfer processes are studied in various thickness P3HT films; and enhanced interchain electronic energy transfer was confirmed by fluorescence anisotropy measurements.
