Spectroscopic properties of Nd3+ in barium fluoroborophosphate and barium fluorosulphatephosphate glassy matrices have been analyzed by fitting the experimental data with the standard Judd-Ofelt theory. Various spectroscopic parameters viz. Radiative transition probabilities, radiative decay time, stimulated emission cross sections and quantum efficiency of the principal fluorescence transition from the 4F3/2 metastable level are obtained. Results show that addition of borate content to the fluorophosphate matrix will reduce the fluorescence spectral properties of Nd3+, whereas the influence of sulphate content is to improve the fluorescence spectral properties over a considerable extent. A comparison of the radiative properties of two hosts with that of fluorophosphate shows that the performance of the fluorosulphatephosphate matrix is superior and hence can be considered as possible candidate for solid state laser amplifiers.
