Lithium borate glasses activated with specific concentrations of Ce³⁺ ions have been processed by melt quenching technique. X-ray diffraction and SEM with EDAX carried out structural and surface morphology with elemental confirmation respectively. The nebulous nature of glassy matrices have been affirmatively confirmed by XRD and it was corroborated with SEM analysis. A distinguished absorption band is noticed in the ultraviolet region and the photoluminescence spectra displays a broad and intense blue emission band in the region from 395 nm to 570 nm which is centered at 447 nm (5d→4f) by exciting with 350 nm in Ce³⁺: LBZ glassy matrices. The dazzling blue emission intensity was significantly ameliorated by improving the addition of Ce³⁺ ion concentration in the glass matrix. The blue emission intensity has been found to be decreased at higher concentrations due to concentration quenching and the optimal concentration of Ce³⁺ ions is estimated to be 0.5 mol%. The fluorescence decay time has been evaluated as 0.86 ms from the decay profile of 0.5 mol% Ce³⁺: LBZ glass. Chromaticity coordinates were determined from the luminescence spectra, which are found to be falls in the bright blue region. The obtained blue emission CIE coordinates are close to standard EBU and NTSC coordinates for blue illumination. In view of these spectral features, 0.5 mol% Ce³⁺: LBZ glass could be recommended as promising candidate for the applications of blue emissive photonic devices.

已通过熔融淬火技术处理了以特定浓度的Ce ³⁺离子活化的硼酸锂玻璃。EDAX的X射线衍射和SEM分别进行了结构和表面形态学分析，并得到了元素证实。X射线衍射已经肯定地证实了玻璃状基质的雾状性质，并通过SEM分析得到了证实。通过在Ce ^3中以350 nm激发，在395 nm至570 nm区域内可见明显的吸收带，并且光致发光光谱在395 nm至570 nm区域显示出宽而强烈的蓝色发射带。⁺：LBZ玻璃基质。通过改善Ce ³⁺的添加，显着改善了令人眼花blue乱的蓝色发光强度。玻璃基质中的离子浓度。已经发现由于浓度猝灭，在较高浓度下蓝色发射强度降低，并且Ce ³⁺离子的最佳浓度估计为0.5mol％。根据0.5 mol％Ce ³⁺：LBZ玻璃的衰减曲线，荧光衰减时间估计为0.86 ms 。由发光光谱确定色度坐标，发现其落在亮蓝色区域中。所获得的蓝色发射CIE坐标接近用于蓝色照明的标准EBU和NTSC坐标。考虑到这些光谱特征，可以推荐将0.5mol％的Ce ³⁺：LBZ玻璃用作蓝色发光光子器件的有前途的候选物。
