Abstract ： Optical properties of Pr3+ doped in Y2 SiO5 , including absorption spectra, emission spectra, and fluorescence decay, have been investigated with a special attention in the UV region. Broad band (270--350nm) UV fluorescence assigned to the transitions 4f5d → 4f2 3 HJ , 3 FJ is found. The spontaneous transition probabilities in the 4f2 intraconfiguration are calculated by utilizing the Judd--Ofelt theory, by which three phenomenological parameters (Ω2 , Ω4 , Ω6 ,) are obtained by fitting the absorption spectra. For the evaluation of transition probability of the interconfiguration 4f5d → 4f2 , a formula for electric dipole transition is employed. In comparison of the measured fluorescence lifetime with the calculated spontaneous radiative lifetime, the fluorescence quantum efficiency is deduced.
