Abstract :Stability effects in photoconductivity insert ignore into journalissuearticles values(PC); rise and decay have been studied over a period of 2 years in thin films of insert ignore into journalissuearticles values(Cd-Pb);S:LiF, La/Pr and insert ignore into journalissuearticles values(Cd-Zn);S: LiF,La/Pr and have been found quite stable; however, those of CdS are not that stable. Results of annealing effect are also included, which present more stable values. XRD studies show prominent lines of base materials. Further, XRD and SEM studies show the particle sizes are in the nanometer range. Results of optical absorption spectra have been used to evaluate the band gap of the materials. Effect of thickness of the Ag electrode has also been included.
