The thermoluminescence of Yb-doped GaS upon UV irradiation has been studied in the course of linear heating. The observed thermostimulated emission bands are found to be complex and to consist of several strongly overlapping partial maxima. The activation energies, capture cross sections, frequency factors and concentrations of the trap levels responsible for these peaks are determined.
