采用固相反应法合成了Tb 3+离子激活的Li 4SrCa（SiO 4）2荧光粉。用XRD检测了相杂质。详细研究了不同Tb ~（3+）离子浓度样品的光致发光（PL）激发光谱、室温和高温发射光谱以及衰减曲线。交叉松弛和Inokuti-Hirayama模型被用来分析实验结果。Li 4SrCa（SiO 4）2：xTb 3+是热稳定且颜色可调的磷光体。
Tb3+ions activated Li4SrCa(SiO4)2phosphors were synthesized using a solid state reaction method. The phase impurity was checked by XRD. The photoluminescence (PL) excitation spectrum, emission spectra at room and high temperature, decay curves of samples with different Tb3+ions concentration were studied in detail. Cross-relaxation and the Inokuti–Hirayama model were used to analyze the experimental results. Li4SrCa(SiO4)2:xTb3+are thermally stable and color tunable phosphors.
