摘要：
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 P-6(3/2) bands of Sm3+ produces a strong orange and red emission from the (4)G(5/2) level. The results show noticeable differences between glass precursor, bulk and nanocrystalline Sm3+:La2Te4O11 in luminescence experimental data. (C) 2018 Elsevier B.V. All rights reserved.
