摘要：

A relative photosensitivity factor S equal to 1430 is observed due to incorporation of Y in CdS. Dye-treatment enhances this value to 4516. A charge-transfer mechanism may be considered to be responsible for this process. Superliner photoconductivity and thermal quenching observed in the temperature range 133-366 K are explained in terms of a two-centre model.
