The single crystal of Ho3+ doped Sr3Y2(BO3)4 has been grown by the Czochralski method.The absorption spectrum,fluorescence spectrum,and fluorescence decay curve of the crystal were measured at room temperature.The fluorescence spectrum in the range of 450-800 nm is dominated by 5F5 → 5Is and 5S2,5F4 → 5I8 transitions.According to the Judd-Ofelt theory,the intensity parameters Ωt (t =2,4,6) were calculated,and the spontaneous transition probabilities,fluorescence branching ratios and radiative lifetimes were obtained.The fluorescence lifetime of the 5F5 →5I8 transition for Ho3+:Sr3Y2(BO3)4 crystal is about 57 ns.
