Abstract

KGdF4 polycrystalline doped with the different concentration of Sm3+ ions were synthesized by hydrothermal technique. Thermoluminescence (TL) glow curves of samples were measured in the range from 50 oC to 400 oC after irradiating beta, neutron and X-ray radiations. The response of TL intensity to impurity concentration and neutron dose were studied in detail. The TL kinetic parameters such as activation energy (E) and frequency factor (s) were estimated by using the method of heating rate variation.

Keywords: KGdF4 polycrystalline, Thermoluminescence.
