Abstract

Lu2O3 is a novel material for high-power solid-state lasers due to its high thermal conductivity. In present work, Nd3+:Lu2O3 transparent ceramics with different Nd3+ doping concentration (CNd = 0, 1at%, 3at% and 5at%) were fabricated by spark plasma sintering, using commercial oxides as raw materials and LiF as sintering aid. The effect of Nd3+ doping concentration on phase, sintering property, microstructure and optical properties was investigated. X-ray powder diffraction (XRD), scanning electron microscopy (SEM), UV-VIS-NIR spectroscopy, and fluorescence spectroscopy were used for characterization. The results show that the sintered body exhibits pure Lu2O3 phase even with high Nd3+ doping concentration (5at%). The Nd3+ doping concentration has little influence on densification behavior and microstructure of Nd3+:Lu2O3 ceramics. All the sintered bodies have a high relative density above 99.5% and excellent transparency, in which 3at% Nd3+:Lu2O3 body shows highest transmittance, with values of 82.7% and 83.2% at 1064 and 2000 nm, respectively. Nd3+:Lu2O3 transparent ceramics show strongest emission bands located at 1076 and 1080 nm, which are attributed to the 4F3/24I11/2 transition of Nd3+ ions. The emission intensity and decay time decrease with increasing Nd3+ doping concentration, which indicates concentration quenching.
