采用紫外-可见-近红外吸收光谱（UV-Vis-NIR）、拉曼光谱（Raman）和光致发光（PL）等技术，研究了Nd ~（3+）离子掺杂的适用于先进光学器件的碲酸盐多元玻璃TeO_2-TiO_2-ZnO（TTZ）。我们不仅进行了实验表征，而且理论上预测的Nd 3+掺杂TTZ玻璃的PL性能，通过使用Judd-Ofelt理论。研究了玻璃熔体制备过程中玻璃中残留羟基和坩埚类型对TTZ玻璃结构和光学性能的影响。我们发现，使用一个Pt坩埚增加了三角双锥TeO 4的网络连接结构的情况下相比，一个Al 2 O3坩埚。此外，减少TTZ玻璃中OH基团的含量也改善了Nd 3+掺杂TTZ玻璃的光学性能，Nd 3+：4F 3/2→ 4 I11/2在1075 nm处的光谱优值达到8.71 × 10− 24 s cm 2，表明具有较低羟基含量的Nd 3+掺杂TTZ玻璃在激光或有源光学应用中具有良好的前景。
This paper describes Nd3+-ions doped multicomponent tellurite glasses TeO2-TiO2-ZnO (TTZ) applicable to advanced optical devices, which were characterized by UV–Vis-NIR absorption, Raman, and photoluminescence (PL) techniques. Not only did we perform experimental characterizations but also theoretically predicted the PL properties of Nd3+-doped TTZ glasses by using the Judd-Ofelt theory. The influence of the residual hydroxyl (OH) groups and types of crucible used in the melt preparation on the structures and optical properties of TTZ glasses was investigated. We found that the use of a Pt crucible increased the network-connecting structures of trigonal bipyramidal TeO4compared to the case of a Al2O3crucible. Moreover, reducing the OH groups in TTZ glasses improved the optical properties of Nd3+-doped TTZ glass, and a higher spectral figure of merit of 8.71 × 10−24s cm2for Nd3+:4F3/2→4I11/2emission at 1075 nm could be achieved, indicating that Nd3+-doped TTZ glass with lower hydroxyl content is promising for laser or active optical applications.
