It was shown that one or two molecular layers of the dye on the of surface zinc oxide gave highest photoresponse. The conductivity change occured by dye-evaporation in the dark and under the illumination with wavelengths in dye-sensitized region was also observed. Conductivity of zinc oxide layer was always increased extremely by dye-evapotration. The change of the surface potential difference of zinc oxide by dye-evaporation was also observed. The surface potential of zinc oxide positively increased and saturated with the increase of the mass of dye evaporated. These experimental results indicate that dye and zinc oxide make an electronic contact and it is thought that from polarity of the contact electrons in the dye are injected into zinc oxide layer, when dye is evaporated on zinc oxide. These experimental results support the presence of electronic contact between the dye and zinc oxide, and suggest the "electron transfer mechanism" about dye- sensitization., Article, 信州大学工学部紀要 26: 95-105 (1969)}, pages = {95--105}, title = {色素を蒸着添加した酸化亜鉛の諸特性}, volume = {26}, year = {1969} }
