Abstract

Thermoluminescence measurements at linear heating rates of 0.025 and 0.100 K°/sec. on the ZnF2:Mn phosphor with electron and ultraviolet excitation have been made as a function of activator concentration and crystallization temperature. Five individual glow peaks between 100°K and 700°K have been clearly resolved. The relative intensities and widths of the peaks are independent of the type of excitation and activator concentration but are strongly dependent on crystallization temperature and subsequent annealing. A detailed theoretical analysis of the glow peak at 350°K with the 0.025 K°/sec. heating rate indicates that the most probable mechanism of the kinetics is basically first order with a strong probability of retrapping. The depths of the electron traps responsible for the complete thermoluminescence are estimated, and the possibilities of the precise physical nature of individual electron traps in ZnF2:Mn are discussed in the light of the glow data.
