Abstract

A relative photosensitivity factor,S, of the order of 5000 is observed due to the incorporation of lanthanum in CdS. Dye treatment enhances this value by 10 000. A charge transfer mechanism is considered applicable to this process. Superlinear photoconductivity and thermal quenching observed in the studies from 133 to 366 K are explained in terms of a two-centre model.
