Research Abstract

Crystalline CdS and CdSe were prepared by chemical bath deposition. In order to prepare CdS films on glass substrates, the addition of triethanolamine together with ammonia into cadmium precursor solution was necessary. On the other hand, the preparation of crystalline CdSe particles was essential to add sodium sulfite as a stabilizing agent for selenium ions and sodium dicarboxylate as a complexing agent for cadmium ions into precursor solution. The electrical conductivity and the mobility of CdS films increased with the increase of Cu dopant under dark and visible light irradiation. Under ultraviolet radiation, however, it was found that the electrical conductivity and the mobility decreased with the increase of addition of Cu. The carrier concentration was constant, in spite of the addition of Cu dopant and the irradiation of light. In the case of CdSe particles, the ratio of cadmium to selenium in the samples decreased with an increase of the concentration.of selenourea in the precursor solutions. The band-gap energy of CdSe with an atomic ratio(Cd/Se) of 1 showed a value of 1.74eV, but that with the ratio of 2.3 gave a slightly smaller value of 1.42eV.
