摘要：

A single crystal 1.85 at% Dy3+:NaGd(MoO4)(2) was grown by the Czochralski method and spectroscopic properties of the crystal were investigated. Room temperature polarized absorption spectra were analyzed by the Judd-Ofelt theory. Then the intensity parameters, spontaneous transition probabilities, branching ratios, and radiative lifetimes of Dy3+ ions in the crystal were obtained. The peak polarized emission cross-sections for the F-4(9/2) -> H-6(13/2) transition were calculated to be 1.62 x 10(-20) and 1.35 x 10(-20) cm(2) for pi and sigma polarizations respectively by the Fuchtbauer-Ladenburg equation. The fluorescence decay curve and quantum efficiency of the F-4(9/2) multiplet were measured to be 156 mu s and 74%, respectively. The experimental results show that the Dy3+:NaGd(MoO4)(2) crystal can be pumped directly by commercially available 450 nm blue laser diodes and may be a promising yellow laser material.
