Abstract
Photoelectron emission from Au was measured in ambient atmosphere under irr adiation of ultraviolet light from a Hg lamp. The emission was greatly infl uenced by the adsorption of organic and inorganic vapors. The adsorption of cyclohexene showed a significant, but gradual increase of photoelectron em ission. On the other hand, the adsorption of acetone reduced photoelectron emission irreversibly to near zero. The change of the photoelectron emissio n could be interpreted in terms of the change of the work function.
