Abstract

The basic differential equations describing thermally stimulated luminescence (TSL) and conductivity (TSC) in insulating crystal are numerically solved for different sets of recombination and trapping parameters without any additional assumptions. As a result different TSL and TSC characteristics are calculated for the case of temperature-dependent recombination and trapping coefficients. The results of calculations show that the assumption of quasi-equilibrium often used in the approximative description of the TSL and TSC phenomena is correct if the density of recombination centers in crystal is higher than 10¹⁴ cm^-3.
