Structural, optical and thermoluminescence study of Dy3+ ion doped sodium strontium borate glass

In the present work physical, optical and thermoluminescence studies of Dy3+ ion doped sodium strontium borate glasses have been reported. XRD study confirms the amorphous nature of glass and the increasing concentration of Dy2O3 results in broadening and shifting of the XRD peak. FTIR shows no change in structure with the inclusion of Dy2O3 but the optical band gap is sensitive to dopant concentration. Glow curve possess single prominent peak in the temperature range 390-393 K and the glass sample with 0.4 mol% Dy2O3 concentration has the most appropriate TL response. The Glow curve width also changes with the dopant concentration. The calculation of kinetic parameters shows that all the glass samples exhibit second order kinetics. (C) 2017 Elsevier B.V.
