Abstract

The absorrption spectra, fluorescent spectra and fluorescent lifetime of Li-La phosphate glasses are measured. Radiative transfer of energy between Cr3+→Nd3+ ions in Li-La phosphate glasses are studied. Energy transfer efficiency from Cr3+→Nd3+ ions in Li-La phosphate is 38%, the optimum doping concentration of Nd3+is 2×1021cm-3 and Cr2O3 content is ≥0.1 wt%.
