Abstract

Sr2SiO4:Dy3+ phosphors were prepared by a conventional solid-state reaction method. In this present study, thermoluminescence (TL) study of Dy3+  doped Sr2SiO4 phosphor is reported. The crystal structure of the prepared phosphor has an orthorhombic structurewith space groupPnma and average crystalline sizes could be calculated as 34 nm. The Fourier-Transform Infrared spectroscopy (FTIR) confirms the present elements in Sr2SiO4:Dy3+ phosphor and energy band gap were founded by optical absorption spectra.Thermoluminescence study was carried out for the phosphor which shows a single glow curve.The kinetic parameter has been calculated by using Chen’s glow curve method.
