Abstract
Photoconductive CdS:Y films prepared by chemical bath technique show photocurrent to dark current ratios of the order of 105. From scanning electron micrographs, a combination of crystalline and noncrystalline growths are inferred. In the presence of Y a maximum transmission of the order of 60% is found. Traps at depths 0.68 and 0.72 eV are found effective.
