Abstract
Herein, we have reported the thermoluminescent properties of Dy3+ activated Sr2ZnSi2O7 phosphors synthesized via solid-state reaction method. The synthesized phosphors were characterized via X-ray diffraction, transmission electron microscopy, Fourier transform infrared spectroscopy and thermoluminescent techniques. Thermoluminescence (TL) glow curve analysis of prepared Dy3+-activated Sr2ZnSi2O7 phosphors were recorded for different UV exposure time and found linear response with dose. The TL glow curve shows composite in nature and broad glow curve centered at 309°C were found. Composite TL glow curve extracted by glowfit program using computerized glow curve deconvolution (CGCD) technique and corresponding kinetic parameters are calculated. The obtained results indicate that the synthesized phosphors find potential applications in the fields of dosimetric applications.
