Abstract
In this paper, we have reported the thermoluminescence (TL) glow curves and kinetic parameters, activation energy; order of kinetics, frequency factor of (Zn, Cd)S mixed phosphor under UV irradiations. The sample was prepared by solid state reaction method, thereafter the TL glow curves were recorded for different doses of UV exposure at heating rate 10°C s−1. The sunthesized phosphor exhibit the TL glow peaks at 136°C for heating rate 10°C s−1 at different doses 5 min; 10 min; 15 min of UV exposure. The kinetic parameters activation energy E; order of kinetics b; frequency factor S of synthesized phosphor have been calculated by using peak shape method and also calculated the trap depth was determined using different formula. Here prepared phosphor shows linear response with dose so we interpreted that these is may be useful for dosimetric material. Also the TL glow curve recorded for different heating rate 2 to 10°C s−1.
