Abstract

The anion composition dependence of the characteristic glow peak temperature of europium doped KCl$_{0.50}$KBr$_{0.25}$RbX$_{0.25}$:Eu$^{2 + }$ (X=Cl, Br) mixed crystals are studied. Each material shows a thermoluminescence glow curve consisting of two main glow peaks with a temperature is between KCl:Eu$^{2 + }$ and KBr:Eu$^{2 + }$. The most intense is related to the F center destruction as occur in the case of KCl:Eu$^{2 + }$ crystals and its characteristic temperature depends strongly on the halogen composition. This behavior confirms that the temperature of the F-H centers recombination in this type of materials depends more on the proportion of anions. From these results, a generalized rule to obtain the temperature from averaging the characteristic temperature as function of the composition is discussed.
