Abstract

The fabrication of transparent Sc₂O₃ ceramics by hot pressing of self-propagating high-temperature synthesized powders was developed. The effect of lithium fluoride aid and calcination temperature on the powders properties was investigated. After calcination at 1100 °C, uniformly shaped Sc₂O₃ nanopowders with a primary particle size of less than 50 nm were obtained. Using the prepared powders doped with LiF fully dense optical quality Yb:Sc₂O₃ transparent ceramics were fabricated by hot pressing. The in-line transmittance of the sample reached 78% at a wavelength of 800 nm. Laser generation with a maximum efficiency of 24% was achieved using a 2% Yb: Sc₂O₃ sample.

LiF助烧剂热压Yb:Sc2O3激光陶瓷

研究了自蔓延高温合成粉末热压制备透明Sc2O3陶瓷的工艺。研究了氟化锂助剂和煅烧温度对粉末性能的影响。在1100°C下煅烧后，获得了一次粒径小于50nm的形状均匀的Sc2O3纳米粉末。利用制备的掺有LiF的粉末，通过热压法制备了光学质量完全致密的Yb:Sc2O3透明陶瓷。样品在800nm波长下的在线透射率达到78%。使用2%Yb:Sc2O3样品实现了最大效率为24%的激光产生。
