Ca₃La_3-x(BO₃)₅:xTb (x = 0.005 to 0.10) phosphors were synthesized by the sol-gel process. The formation of the sol-gel products was confirmed by X-ray diffraction (XRD) analysis. The samples were also characterized by FTIR spectroscopy to study the nature of bonding between boron and oxygen ions. The luminescence properties of the synthesized products were examined under ultraviolet (UV) and vacuum UV (VUV) excitations. The phosphor exhibited green luminescence with the optimum emission peak centered at 544 nm for UV and VUV excitation. The color purity of the sample with optimum Tb concentration was 63.63%. The prepared phosphors are a good option for the green-emitting component in plasma-display panels (PDPs).

通过溶胶-凝胶法合成Ca ₃ La _3-x（BO ₃）₅：xTb（x = 0.005至0.10）磷光体。通过X射线衍射（XRD）分析确认了溶胶-凝胶产物的形成。还通过FTIR光谱对样品进行了表征，以研究硼和氧离子之间的键合性质。在紫外线（UV）和真空紫外线（VUV）激发下检查了合成产物的发光特性。该磷光体表现出绿色发光，对于UV和VUV激发，最佳发射峰集中在544 nm处。具有最佳Tb浓度的样品的色纯度为63.63％。制备的磷光体是等离子显示面板（PDP）中绿色发射组件的不错选择。
