【 摘 要 】

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.
