In this report, Ba_1.3Ca_0.7SiO₄: Tb³⁺ phosphors were prepared by the low-temperature solution-combustion method. The structural properties of the Ba_1.3Ca_0.7SiO₄: Tb³⁺ phosphors were examined by XRD and SEM. The phosphorescence spectra of low Tb³⁺ doped ceramics have revealed prominent blue and green emissions from ⁵D₃ and ⁵D₄ exciting levels to ⁷F_j ground state respectively. The calculated CIE color coordinates confirmed that varying the content of Tb³⁺ makes the luminescence color of Ba_1.3Ca_0.7SiO₄: Tb³⁺ to be tuned from blue to green region. The highest emission intensity at 231 nm excitation wavelengths signifies its potential applicability in the fields of lighting and displays.

在此报告中，通过低温溶液燃烧法制备了Ba _1.3 Ca _0.7 SiO ₄：Tb ³⁺荧光粉。通过XRD和SEM检查了Ba _1.3 Ca _0.7 SiO ₄：Tb ³⁺荧光粉的结构性能。低Tb ³⁺掺杂的陶瓷的磷光光谱已显示出分别从⁵ D ₃和⁵ D ₄激发能级到⁷ F _j基态的显着蓝色和绿色发射。计算出的CIE颜色坐标确认了Tb含量的变化³⁺使Ba _1.3 Ca _0.7 SiO ₄：Tb ³⁺的发光颜色从蓝色变为绿色。在231 nm激发波长处的最高发射强度表明其在照明和显示器领域的潜在适用性。
