Composition dependence of glow peak temperature in KCl_{1 <i>x</i>}Br_<i>x</i>doped with divalent cations

Abstract

Thermoluminescence measurements of β-irradiated Eu2+- and Ca2+-doped KCl1−xKBrx solid solutions excited at room temperature have been carried out to identify the effect of composition on the glow peaks. A typical glow peak has been distinguished for each composition. A linear dependence of its temperature on the composition x has been found. These results indicate that for divalent impurity-doped alkali halide solid solutions these glow peak temperatures are mostly dependent on the lattice constant of the host than on the size of the anion or impurity cation.
