Optical absorption and emission spectra are presented for Dy/sup 3 +/ ions in fluorozirconate (ZBLA) glass. The measured oscillator strengths and radiative rates for several transitions are compared with calculated values. Radiative transition rates for the excited states are determined by using the Judd-Ofelt theory (B.R. Judd, Phys. Rev. 127, 750 (1962); G.S. Ofelt, J. Chem. Phys. 37, 511 (1962)). Thermal evolution of the radiative rate is observed for the /sup 4/F/sub 9/2/ level and is well accounted for by Start level thermalization. Energy transfer effects are responsible for the nonradiative transitions.
