We synthesized pure and Pb²⁺ ion-doped Li₆Gd(BO₃)₃ phosphors via the solid-state reaction method at 700^oC for 5 h in air. The phase analysis of the synthesized materials was determined using DTA/TGA, XRD, and FTIR. The photoluminescence characteristics of pure and Pb²⁺-doped phosphors were investigated at room temperature using a photoluminescence spectrophotometer. The emission and excitation bands of Pb²⁺-doped Li₆Gd(BO₃)₃ were observed at 313 and 242 nm, respectively. The dependence of the PL intensities on the Pb²⁺ concentration for the Li₆Gd_1–xPb_x(BO₃)₃ (0.005 ≤ x ≤ 0.025) phosphors was also studied. The highest emission intensity was obtained from 0.02 mole Pb²⁺-doped Li₆Gd(BO₃)₃.

我们通过固相反应法在700 ^o C下在空气中5 h合成了纯的和Pb ²⁺离子掺杂的Li ₆ Gd（BO ₃）₃荧光粉。使用DTA / TGA，XRD和FTIR确定了合成材料的相分析。使用光致发光分光光度计在室温下研究了纯的和Pb ²⁺掺杂的磷光体的光致发光特性。分别在313和242nm处观察到了掺Pb ^2+的Li ₆ Gd（BO ₃）₃的发射带和激发带。Li的PL强度对Pb ²⁺浓度的依赖性_{还研究了6} Gd _1–x Pb _x（BO ₃）₃（0.005≤x≤0.025）荧光粉。从0.02摩尔的Pb ²⁺掺杂的Li ₆ Gd（BO ₃）₃获得最高的发射强度。
