Abstract

The spectroscopic properties of (Y0.92xLa0.08Ndx)2O3 transparent ceramics were investigated. According to three intensity parameters (Ω2,Ω4,Ω6) fitted by the Judd–Ofelt theory, the spectroscopic quality parameter (XNd), branching ratio (βJ,J), and quantum efficiency (η) of Nd3+ were determined. It was found that XNd of the host, owing to the additive La2O3, was decreased from 1.6 to 0.46; thus βJ,112 was increased from 46% to 56.82%. A figure of merit of the specimens was discussed and compared with Nd:YAG transparent ceramic.
