摘要：

High photosensitive CdS:ZnCdS structure was formed by screen printing and high temperature sintering of CdS and ZnCl2 powders. The sintering of the film at high temperatures resulted in the formation of ZnCdS nanoparticles in a CdS matrix by an ion interchange reaction followed by a solid state reaction. The photosensitivity of the structure depends on parameters like initial film composition (ZnCl2 to CdS ratio), sintering temperature and sintering time. The influence of these parameters on the dark and photocurrent characteristics of CdS:ZnCdS structure is explained by taking into consideration the presence of deep acceptor centers related to Cd and Zn vacancies, shallow donor levels due to S vacancies in the films and recrystallization of ZnCdS nano particles.
