摘要：

The intensity of photoluminescence (PL) emission bands in CdS:Ag:Cl depends on the added Ag (1016-1020 cm-3) and Cl (1016-1019 cm-3) concentration and the partial pressure of Cd or S is measured. It is shown that the intensity of PL bands is a power function of the silver and chlorine concentration and the partial pressure of the components. The comparison between the experimental and theoretical curves permits one to determine the nature of the radiative and non-radiative recombination centres of Ag and Cl in CdS:Ag:Cl. © 1990.
