Paper Abstract
A novel sol-gel process has been used to prepare homogeneous, fully dense, cylindrical samples of neodymium-doped silica and neodymium-aluminum-doped silica. The absorption and emission spectra, fluorescent lifetimes and quantum yields of all samples were measured. The quantum yields of Nd2O3-SiO2 samples were very low due to clustering of the Nd in the silica matrix. The incorporation of alumina eliminated the clustering and quantum yields up to 55% were obtained. We showed that these quantum yields of less than unity were caused by residual OH quenching of the Nd fluorescence. The fluorescent properties were unchanged when the OH was replaced with OD. One sample was demonstrated to laser under laser pumping.
