Absorption spectra, emission spectra and excitation spectra of Er3+ ions in fluoroindate glasses were measured. The Judd Ofelt parameters Ωt(t=2,4,6) of this glasses were calculated. The calculation results of luminescence properties (Ajj′, σр, β, τ0) of Er3+ ions in fluoroindate glasses were given, and compared with Er3+ doped fluorozirconate glass, the influence of glass hosts on the luminescenceof Er3+ ions was explained.
