Thermoluminescence properties of aluminium oxide doped strontium, lithium and germanium prepared by combustion synthesis method
In this work, Al2O3 doped with Sr, Li and Ge was prepared by combustion synthesis techniques for thermoluminescent (TL) ionizing radiation dosimetry applications. Dopants sample concentration were varied from 0.1 mol% to 5 mol% in order to study the effect of the concentration on the TL response. Th...
