摘要：

Pr3+ doped La2CaB10O19 crystal were grown by the top-seeded solution growth(TSSG) method.The absorption spectra,emission spectra and lifetime were measured at room temperature.The J-O parameters(Ωt,t=2,4,6),the radiative transition probabilities AJ,J’,oscillator strengths PJ,J’,radiative lifetime τ,fluorescence branch ratios βJ and the value of integrated emission cross section have also been calculated.Five main absorption bands,3H4 to 3P1+3P2,3P0,1D2,3F3 + 3F4 and 3F2,were observed in the absorption spectra.The 1G4 absorption band was not observed.A very strong emission band at 601 nm(1D2→3H4) was observed in the emission spectra.The experimental lifetime for this level was compared with that obtained theoretically by using J-O approach.
