Abstract

We demonstrate new series of heavy metal containing fluorophosphate glass system. The fluorescence and nonradiative properties of Nd3+ ions are investigated as a function of Nd2O3 concentration. The variation of intensity parameters Ω2, Ω4, andΩ6 is determined from absorption spectra. The spontaneous probability (A) and branching ratio (β) are determined using intensity parameters. The emission cross sections for the 4F3/2 → 4I13/2 transition, which is calculated by Fuchtbabauer-Ladenburg method, decrease from 6.1 × 10−21 to 3.0 × 10−21 (pm2) and those for the 4F3/2 → 4I11/2 transition decrease from 3.51 × 10−20 to 1.7 × 10−20 as Nd2O3 concentration increase up to 3wt%. The nonradiative relaxation is analyzed in terms of multiphonon relaxation and concentration quenching due to energy transfer among Nd3+ ions. Finally, the above results obtained at 1wt% Nd2O3 are compared with some of reported laser host glasses which indicated the potentials for broadband-amplifiers and high-power laser applications.
