Abstract

Nd^3 +-doped sesquioxide ceramics have the advantages of high thermal conductivity and low phonon energy but are limited by their low transmittance and short lifetime. In this study, Nd:LuScO₃ transparent ceramics with different Nd³⁺ concentrations were successfully fabricated by vacuum sintering, followed by hot isostatic pressing using a ZrO₂ sintering aid. The effects of Nd³⁺ concentration on the microscopic morphology, crystal structure, and optical properties were investigated. Experimental results showed that the 0.5 at% Nd:LuScO₃ ceramic had the highest transmittance and longest fluorescence lifetime, reaching 81.5 % at 1500 nm and 211 μs, respectively. Furthermore, the quasi-continuous wave laser operation of the Nd:LuScO₃ ceramic was achieved for the first time, with a peak power of 0.6 W and a slope efficiency of 11.3 %, demonstrating promising prospects for solid-state laser gain media.

Nd:LuScO3透明陶瓷的制备、光谱学和激光操作

掺Nd3 +的倍半氧化物陶瓷具有高导热性和低声子能量的优点，但受其低透射率和短寿命的限制。本研究成功制备了不同Nd3+浓度的Nd:LuScO3透明陶瓷，采用真空烧结，然后用ZrO2助烧结剂进行热等静压。研究了Nd3+浓度对材料显微形貌、晶体结构和光学性能的影响。实验结果表明，0.5 at% Nd:LuScO3陶瓷的透过率最高，荧光寿命最长，分别在1500 nm和211 μs处达到81.5 %。此外，还首次实现了Nd:LuScO3陶瓷的准连续波激光工作，峰值功率为0.6 W，斜率效率为11.3 %，显示了固体激光增益介质的良好前景。

期刊介绍： The Journal of the European Ceramic Society publishes the results of original research and reviews relating to ceramic materials. Papers of either an experimental or theoretical character will be welcomed on a fully international basis. The emphasis is on novel generic science concerning the relationships between processing, microstructure and properties of polycrystalline ceramics consolidated at high temperature. Papers may relate to any of the conventional categories of ceramic: structural, functional, traditional or composite. The central objective is to sustain a high standard of research quality by means of appropriate reviewing procedures.
