Abstract Nd3+ doped Y3ScxAl5-xO12 (x = 0.05, 0.5, 1) single crystals were successfully grown by the micro-pulling-down (μ-PD) technique. The effect of compositional parameter x on the structure, absorption, emission and fluorescence lifetime of Nd:Y3ScxAl5-xO12 crystals was studied. The Nd3+ concentration in the core increased with increasing of compositional parameter x. The full width at half maximum (FWHM) of the emission band centered at 1064 nm was calculated to be 6.1, 7.1, and 7.3 nm for x = 0.05, 0.5 and 1, respectively. The fluorescence lifetimes of 4F3/2 levels are 259.3, 269.6, and 276.9 μs for x = 0.05, 0.5, and 1, respectively. The results indicate that the Nd:Y3ScxAl5-xO12 crystals are promising materials for laser output.

摘要 通过微下拉（μ-PD）技术成功生长了 Nd3+ 掺杂的 Y3ScxAl5-xO12 (x = 0.05, 0.5, 1) 单晶。研究了成分参数x对Nd:Y3ScxAl5-xO12晶体结构、吸收、发射和荧光寿命的影响。岩心中 Nd3+ 的浓度随着成分参数 x 的增加而增加。对于 x = 0.05、0.5 和 1，以 1064 nm 为中心的发射带的半峰全宽 (FWHM) 分别计算为 6.1、7.1 和 7.3 nm。对于 x = 0.05、0.5 和 1，4F3/2 能级的荧光寿命分别为 259.3、269.6 和 276.9 μs。结果表明，Nd:Y3ScxAl5-xO12 晶体是一种很有前途的激光输出材料。
