Ageing effect on the thermoluminescence of x-irradiated yttrium doped KBr crystals

Thermoluminescence glow curves were recorded on x-irradiated KBr: Y crystals in as grown, aged and quenched conditions. Two glow peaks around 85 and 110 °C were observed in as grown crystals. A marked difference in the glow curve patterns have been observed for aged and quenched crystals. These obse...

Summary:Thermoluminescence glow curves were recorded on x-irradiated KBr: Y crystals in as grown, aged and quenched conditions. Two glow peaks around 85 and 110 °C were observed in as grown crystals. A marked difference in the glow curve patterns have been observed for aged and quenched crystals. These observations are explained on the basis of the state of dispersion of yttrium impurity in KBr lattice.
