本文综述了低价稀土离子(Sm~(2+)、Eu~(2+)、Yb~(2+))在基质晶体中的发光特性,以及用于解释发光过程的理论模型。总结了基质环境对二价稀土离子Sm~(2+)、Eu~(2+)和Yb~(2+)光谱特征的影响。
In this paper, the luminescent properties of rare earth ions (Sm 2 +, Eu 2 + and Yb 2+) in matrix crystals and the theoretical models for explaining the luminescence process are reviewed. The effects of substrate environment on the spectral characteristics of divalent rare earth ions Sm ~ (2 +), Eu ~ (2+) and Yb ~ (2+) were summarized.
