Abstract :
In this Letter the influence of traps on the temperature dependence of PbWO4 (PWO) luminescence is reported in 110–350 K. The electrons trapped at some defects can contribute to the luminescence at special temperature due to the thermally elevation. This conclusion can be drawn from the experimental results of radioluminescence (RL) and thermoluminescence (TL) in the same temperature range. The TL measurements show there are four TL peaks with the first-order kinetic process from 110 to 300 K. The order of kinetics was got through isothermal TL decay curves. The evaluation of trap parameters of TL was obtained using the method of fit. The values of s×exp(−E/kT) acquired by the two methods were coincident.
