Thermoluminescence response of dysprosium doped strontium tetraborate glasses subjected to electron irradiations

The paper presents the thermoluminescence (TL) response of strontium tetraborate glass subjected to electron irradiations at various Dy2O3 concentrations ranging from 0.00 to 1.00 mol%. All glass samples exhibited single broad peak with maximum peak temperature positioned at 170-215 °C. The optimum TL response was found at Dy2O3 concentration 0.75 mol%. This glass showed good linearity and higher sensitivity for 7 MeV compared to 6 MeV electrons. Analysis of kinetic parameters showed that the glasses demonstrate second order kinetic.
