摘要：

Dy3+: Bi4Si3O12 crystal up to phi 25 x 110 mm(2) has been grown by the modified vertical Bridgman method. The absorption spectrum, excitation spectrum, emission spectrum and fluorescence decay curve of Dy3+: Bi4Si3O12 crystal were measured at room temperature. The spontaneous transition probabilities, the branching ratios and the radiative lifetimes have been calculated by means of the Judd-Ofelt theory and compared with the experimental results for the F-4(9/2) emitting level. The decay curve of Dy3+: Bi4Si3O12 crystal has been fitted with the Inokuti-Hirayama energy transfer model which revealed that electric dipole-dipole interaction is responsible for the energy transfer processes in Dy3+ ions doped Bi4Si3O12 crystal.
