Abstract The paper presents the synthesis and spectroscopic properties of Sm3+-doped transparent TeO2-based glass ceramics containing ZnTeO3 and La2Te4O11 nanocrystals. The impact of heat treatment is presented and discussed. X-ray diffraction and transmission electron microscope results demonstrate that nanocrystals are precipitated homogenously among the glass matrix. Excitation in the 6P3/2 bands of Sm3+ produces a strong orange and red emission from the 4G5/2 level. The results show noticeable differences between glass precursor, bulk and nanocrystalline Sm3+:La2Te4O11 in luminescence experimental data.

从 Sm 3+ :La 2 O 3 -ZnO-Na 2 O-TeO 2 玻璃到含有 ZnTeO 3 和 La 2 Te 4 O 11 纳米晶体的透明玻璃陶瓷——热处理对晶体生长和荧光性能的影响

摘要 本文介绍了含有ZnTeO3 和La2Te4O11 纳米晶的Sm3+ 掺杂透明TeO2 基玻璃陶瓷的合成和光谱特性。介绍和讨论了热处理的影响。X 射线衍射和透射电子显微镜结果表明，纳米晶体在玻璃基质中均匀沉淀。Sm3+ 的 6P3/2 波段中的激发产生来自 4G5/2 能级的强烈橙色和红色发射。结果表明，玻璃前驱体、块状和纳米晶 Sm3+:La2Te4O11 在发光实验数据方面存在显着差异。
