Photoeffects involving oxygen-18 at flash-illuminated ZnO and TiO2 surfaces
Abstract
The extent of surface coverage of TiO2 and various zinc oxides by chemisorbed oxygen is compared with relative efficiencies for photodesorption of 18O2, as initiated by 50 µs light pulses and measured by a dynamic mass spectrometer technique. The results can be understood within the framework of the Electronic theory.
