Energy Migration Involving Irradiated Solids
Abstract
Migration of energy from irradiated semiconducting solids to acceptor molecules in contact with the solid surface has been experimentally examined and models have been developed to account for the extent-of-reaction, kinetics and selectivity observed. Fast-detection techniques have been developed to follow, on a time-scale of milliseconds, the kinetics of 'fast' processes initiated at semiconducting metal oxide surfaces by UV-illumination and studies included examination of interfaces between Metal Oxides and Aqueous Electrolytes by ESR, plus the study of Metal Oxide/GAS interfaces by a Dynamic Mass Spectrometric technique. Very low quantum efficiencies were measured for photoassisted processes involving adsorption, desorption or reaction of gases at the flash-illuminated surfaces.
