Abstract
The preparation of sodium phosphate glasses singly and doubly doped with rare earth ions Ce 3+ and Eu 3+ by melt quench method is described. The spectroscopic characterizations of the samples are done using absorption, excitation and emission spectra. The nonradiative energy transfer between trivalent cerium and europium is achieved through the phosphate lattice and the results are incorporated. The main reason of quenching of Ce 3+ ions and the mechanism of energy transfer is mainly electric dipole–dipole in nature for Ce 3+:Eu 3+ system.
