采用改进的固相法在1000 °C下合成了Gd 3+、Dy 3+、Tb 3+和Lu 3+掺杂的BaTiO 3基荧光粉。通过热重分析和差热分析（DTA/TG）对反应条件进行了优化。通过X射线粉末衍射（XRD）表征在空气气氛中获得的反应产物。通过使用SEM仪器进行表面和元素分析。用光致发光分光光度计（PL）记录激发光谱和发射光谱。研究了Gd 3+、Dy 3+、Tb 3+和Lu 3+掺杂BaTiO 3样品的热释光（TL）性质。
Gd3+, Dy3+, Tb3+and Lu3+doped BaTiO3-based phosphors were synthesized with modified solid-state technique at 1000 °C. The optimization of reaction conditions were carried out by thermogravimetry and differential thermal analysis methods (DTA/TG). The reaction products obtained in an air atmosphere were characterized by X-ray powder diffraction (XRD). Surface and elemental analyses were performed by using an SEM instrument. The excitation and emission spectra were recorded by photoluminescence spectrophotometer (PL). The thermoluminescence (TL) properties of BaTiO3samples doped with Gd3+, Dy3+, Tb3+and Lu3+were investigated.
