Single phased CaSrAl₂SiO₇ phosphor singly doped with different concentrations of trivalent cerium and terbium; and co-doped with varying Tb³⁺ concentration were prepared by standard solid state reaction (SSR) method. The crystallinity and particle morphology of the product samples were analysed by using XRD and TEM characterizations. Photoluminescence characterizations of singly doped and co-doped samples were studied in detail. CaSrAl₂SiO₇:Ce³⁺,Tb³⁺ phosphor exhibit a broad blue emission band at 410 nm and some sharp emission bands in blue green and yellow regions, which originate from Ce³⁺ and Tb³⁺ ions, respectively. By increasing the concentration of Tb³⁺ ions while fixing Ce³⁺ concentration in the host lattice energy transfer takes place from Ce³⁺ to Tb³⁺ ions which create luminescence emission in white region. CaSrAl₂SiO₇:Ce³⁺,Tb³⁺ phosphors are proved to be promising candidates for white lighting for outdoor illumination.

单相CaSrAl ₂ SiO ₇荧光粉分别掺杂有不同浓度的三价铈和ter；采用标准固态反应（SSR）法制备并共掺杂了不同浓度的Tb ³⁺。使用XRD和TEM表征分析了产品样品的结晶度和颗粒形态。详细研究了单掺杂和共掺杂样品的光致发光特性。CaSrAl ₂ SiO ₇：Ce ³⁺，Tb ³⁺荧光粉在410 nm处显示较宽的蓝色发射带，并在蓝绿色和黄色区域显示一些尖锐的发射带，其起源于Ce ³⁺和Tb ³⁺离子。通过增加Tb ³⁺离子的浓度，同时固定基质中Ce ^3+的浓度，能量从Ce ³⁺转移到Tb ³⁺离子，从而在白色区域产生发光。事实证明，CaSrAl ₂ SiO ₇：Ce ³⁺，Tb ³⁺荧光粉是用于室外照明的白色照明的有前途的候选材料。
