Fluoroindate glasses co-doped with Pr
3+ /Er3+ ions were synthesized and their near-infrared luminescence properties have been examined under selective excitation wavelengths. For the Pr3+ /Er3+ co-doped glass samples several radiative and nonradiative relaxation channels and their mechanisms are proposed under direct excitation of Pr3+ and/or Er3+ . The energy transfer processes between Pr3+ and Er3+ ions in fluoroindate glasses were identified. In particular, broadband near-infrared luminescence (FWHM = 278 nm) associated to the1 G4 →3 H5 (Pr3+ ),1 D2 →1 G4 (Pr3+ ) and4 I13/2 →4 I15/2 (Er3+ ) transitions of rare earth ions in fluoroindate glass is successfully observed under direct excitation at 483 nm. Near-infrared luminescence spectra and their decays for glass samples co-doped with Pr3+ /Er3+ are compared to the experimental results obtained for fluoroindate glasses singly doped with rare earth ions.
