Thermoluminescence studies on alkali-silicate glass doped with dysprosium oxide for use in radiation dosimetry measurement

Alkali-silicate glass doped with dysprosium oxide was prepared and investigated. Recycled window glass (RWG) was substituted with pure SiO2 chemical as starting material. Physical properties of the glass samples such as density, molar volume and ion concentrations were determined. The thermoluminescence properties such as sensitivity and linearity of the glass samples were investigated. Trap depth parameters were studied using the glow curve shape method. Moreover, the optical absorption of the glass samples was studied with the transition mechanisms of Dy3+ ions. •The physical properties of the glass samples were determined.•Results indicate that the structure of the glass more compactness with doped Dy2O3.•Glass samples doped 0.100mol% of Dy2O3 show highest sensitivity and linearity.•Trap depth parameters were determined by using the glow curve shape method.
