This paper makes a theoretical calculation of the temperature dependence of luminesrcence and photoconductivity for a ZnS:Ag,Al single crystal on the basis of a five-level zone model with two recombination centers and three traps. Experimental values of the level parameters were used in the calculations which were performed on an M-222 computer using the standard programs of the TA-1M translator. The calculated TDL and TDP curves are in satisfactory agreement with the experimental curves, measured with photoexcitation and cathodoexcitation. The calculations serve as a basis for analyzing the different shapes of TDL curves and a treatment is presented for them. Inferences about the characteristic features of luminescence are drawn by using the recombination model of M. Schön and H. A. Klasens in the calculations.
