Solid state blue and green light sources are desirable for high density optical storage, color displays, optoelectronics, and medical diagnostics. In addition to the well-known red emission of Eu3+, strong green, blue, and ultraviolet emissions have been observed in Eu3+ doped ZBLA (57ZrF4·36BaF2·4LaF3·3AlF3) and PIGLZ (43PbF2·17InF3·17GaF3·4LaF3·19ZnF2) fluoride glasses. The intense concentration dependence of these emissions was examined with fluorescence and excitation spectroscopy and found to be caused by nonradiative dipole-quadrupole and dipole-dipole energy transfer between excited and ground state Eu3+ ions. Judd-Ofelt analysis, transfer efficiency, and phonon side band measurements were used to model the fluorescence, energy transfer, and gain cross section for Eu3+ in a ZBLA host.
