Abstract
A novel type of xNd2O3-doped 14.75Gd2O3-23.33Ga2O3-(61.92-x)GeO2 glasses were successfully prepared. The thermal stability of the glass was studied by DSC and the forming ability of the glass was analyzed by XRD. Based on Judd-Ofelt theory, the strength parameters (Ω = 2, 4, 6) and radiation characteristics of the glass were analyzed detailedly by absorption and emission spectra. The results show that when the doping Nd2O3 is 1 mol%, the glasses not only have more stable thermal properties, but also have the best emission spectral intensity at 4F3/2→4I11/2 (1060 nm) with excellent radiative transition probability and stimulated emission cross section (σemis). Furthermore, it is found that the luminescence intensity of the glass ceramics obtained after heat treatment was increased by about 4.5 times due to the formation of GdGaGe2O7 crystal phase. In conclusion, the novel Nd2O3-doped Gd2O3-Ga2O3-GeO2 glass has the potential as a high power laser (1.06 μm) application material.
