Abstract：In the present paper, the room-temperature absorption spectrum of Pr3+-doped transparent oxyfluoride vitroceramics(Pr(0.2)∶FOV )was studied systematically. The optical characterisation of Pr(0.2)∶FOV was performed. The standard and modified Judd-Ofelt theories were used to determine the J-O intensity parameters . The problems with standard Judd-Ofelt theorie for Pr3+ were discussed. Based on the intensity parameters, some predicted optical parameters, such as the spontaneous radiative transition probabilities, radiative lifetimes, branching ratios and integrated emission cross section were calculated. And the application of Pr∶FOV was analyzed. Especially there are large oscillator strength and large integrated emission cross section in the transitions of 3P0→3H4，3P1→3H5 and 3P0→3H6，3P0→3F2. So, they are more worth of attention. The obtained spectroscopic results show the potential application of the Pr3+-doped oxyfluoride vitroceramics for solid-state lasers.
