Photoeffects Involving Oxygen-18 at Flash-Illuminated ZnO and TiO2 Surface.

摘要

The extent of surface coverage of TiO2 and various zinc oxides by chemisorbed oxygen is compared with relative efficiencies for photodesorption of O2(18) as initiated by 50 microsecond light pulses and measured by a dynamic mass spectrometer technique. The results can be understood within the framework of the Electronic theory. (Author)
