本文报道了75NaPO(3)-24CaF(2)-1LNf(3)和75NaPO(3)-20CaF(2)-5LnF(3)中三价稀土离子Ce3+、Pr3+、Nd3+、Sm3+、Eu3+、Gd3+、Tb3+、Dy3+、Ho3+、Er3+、Tm3+和Yb3+的光谱性质。讨论了吸收光谱和发光光谱。吸收光谱中跃迁的偶极强度用三个欧米茄(λ)(lambda=2，4和6)Judd-Ofet强度参数表示。这些唯象参数被用来预测氟磷酸盐玻璃中稀土离子的发光性质。重点研究了镧系元素强度参数的变化趋势。(C)1998 Elsevier Science B.V.保留所有权利。
We describe the spectroscopic properties of the trivalent lanthanide ions Ce3+, Pr3+, Nd3+, Sm3+, Eu3+, Gd3+, Tb3+ Dy3+, Ho3+, Er3+, Tm3+ and Yb3+ in the fluorophosphate glasses 75NaPO(3)-24CaF(2)-1 LnF(3) and 75NaPO(3)-20CaF(2)-5LnF(3) (where Ln = lanthanide ion). Absorption and luminescence spectra are discussed. The dipole strengths of the transitions in the absorption spectrum are parametrized in terms of three Omega(lambda) (lambda = 2, 4 and 6) Judd-Ofelt intensity parameters. These phenomenological parameters are used to predict the luminescence properties of the lanthanide ions in the fluorophosphate glasses. Attention is paid to the trend of the intensity parameters over the lanthanide series. (C) 1998 Elsevier Science B.V. All rights reserved.
