    • Abstract

       

      This paper reports Gd3+, Tb3+ and Lu3+ doped MTiO3 (M = Mg and Sr)-based phosphors which were synthesized by the conventional solid-state reaction method, their crystal structures and luminescence properties were investigated. X-ray diffraction patterns (XRD) showed that phosphors sintered at 1000 °C for 2 h were the pure SrTiO3 and MgTiO3 phases. The optimization of reaction conditions was carried out by thermogravimetry and differential thermal analysis (DTA/TG) methods. Surface and elemental analyses were performed by using SEM instrument. The excitation and emission spectra were recorded by a photoluminescence spectrophotometer (PL). The thermoluminescence (TL) properties of MgTiO3:RE (RE = Gd3+, Tb3+, Lu3+) and SrTiO3:RE (RE = Gd3+, Tb3+, Lu3+) were investigated.
