Abstract

Abstract : Photocurrent of Ag2 S particles decreases in alcohol gases or with CuPc coating and increases in CS2 . This interesting phenomenon is explained through a model of gas adsorption. Abstract : Silver sulfide (Ag2 S) is a traditional semiconductor material, however, the photoelectric properties of Ag2 S particles under different environments are still lacking. In this paper, we reported the preparation of Ag2 S particles and their photoelectric properties under different environments. Results showed that the photoelectric performance of Ag2 S particles was closely related to the environment. It was found that a copper phthalocyanine coating could improve the light response, the mixture of alcohols and air could increase the photoconductivity, and the mixture of carbon disulfide and air could decrease the photoconductivity. The mechanism of the effect of various experimental conditions on photoelectric properties was also discussed.
