摘要
本文利用 Pr^(3+)离子在 Pr_xLa_(1-x)P_5O_(14)晶体中的光谱性质和能级,在考虑~3P_o-~1D_2和~3H_4-~3H_6,~1D_2-~1D_4和~3H_4-~3F_4两个能级对交叉弛豫的情况下,详细研究了 Pr^(3+)离子的荧光动力学过程,给出了~3P_o,~1D_2和~1G_4能级的荧光发射规律。
Based on the spectral properties and energy levels of Pr^(3+)ions in PrxLa_(1-x)P_5 O_(14)crystals,the fluorescence dynamics of Pr^(3+)ions wasstudied by taking consideration of the cross relaxation processes of ~3P_0-~1D_0and ~3H_4-~3H_6、~1D_2-~1G_4 and ~3H_4-~3F_4 energy level pairs.And rules for thefluorescence due to Pr^(3+) ions from ~3p_o,~1D_2 and ~1G_4 energy Ievels weregiven as well.
