| 摘 要： | 采用助熔剂法生长了Ho3+,Yb3+共掺的Ho3+,Yb3+:YAl3(BO3)4(Ho,Yb:YAB)晶体,测量了晶体的室温吸收谱,进而根据Judd-Ofelt(J-O)理论计算了Ho3+在Ho,Yb:YAB晶体中的强度参数、自发辐射几率和积分发射截面等参数,得到强度参数为Ω2=1.50639×10-18cm2、Ω4=4.86489×10-19cm2和Ω6=1.40248×10-19cm2。研究了晶体的荧光特性,并在976 nm激光泵浦下得到了上转换绿色荧光。

| Abstract: | Single crystal of Ho~(3+),ytterbiumcodoped yttrium aluminum tetraborate Ho~(3+),Yb~(3+):YAl_3(BO_3)_4(Ho,Yb:YAB) has been grown by the flux method.The absorption spectra in the visible and NIR regions of Ho,Yb:YAB crystal were measured at room temperature;we calculated the intensity parameters,the spontaneous emission probabilities and stimulated emission cross sections of Ho~(3+) in Ho,Yb:YAB crystal by Judd-Ofelt(J-O) theory.The fluorescence spectra of Ho,Yb:YAB crystal were also measured at room temperature excited by 976 nm laser.The strong NIR emission peaks located at 1 921 nm was observed,and the visible up-conversion luminescence has been found. |
