Abstract

We present a crack-free optically active SiO glass-composite material containing YAG:Ce synthesized via a modified sol-gel technique. A glass-composite material consisting of yttrium aluminum garnet doped with Ce (YAG:Ce) was entrapped into a SiO xerogel. This composite material was prepared using a sol-gel technique with modified gelation and a drying process to obtain crack-free optically active SiO glass. The concentration of the YAG:Ce was from 0.5 to 2.0 wt%. All synthesized samples were characterized via X-ray diffraction (XRD) and scanning electron microscopy (SEM) techniques, confirming their exceptional quality and structural integrity. The luminescence properties of the obtained materials were studied. Overall, the prepared samples' excellent structural and optical quality makes them great candidates for further investigation, or even potential practical application. Furthermore, boron-doped YAG:Ce glass was synthesized for the first time.

摘要

我们展示了一种通过改进的溶胶-凝胶技术合成的无裂纹光学活性SiO玻璃复合材料，其中包含YAG:Ce。一种由掺杂Ce的钇铝石榴石（YAG:Ce）组成的玻璃复合材料被包裹在SiO干凝胶中。该复合材料采用溶胶-凝胶技术，通过改进的凝胶化和干燥工艺制备，以获得无裂纹的光学活性SiO玻璃。YAG:Ce的浓度为0.5至2.0 wt%。所有合成样品均通过X射线衍射（XRD）和扫描电子显微镜（SEM）技术进行表征，证实了它们卓越的质量和结构完整性。对所得材料的发光特性进行了研究。总体而言，所制备样品优异的结构和光学质量使其成为进一步研究甚至潜在实际应用的理想候选材料。此外，首次合成了硼掺杂的YAG:Ce玻璃。
