稀土Eu元素因其优良的光学特性常被作为激活离子广泛应用于无机发光材料中。激活离子的发光性质由自身的价态决定,同时受基质晶体结构影响。不同价态的Eu离子呈现不同的光学特性,当二者共存时有可能得到单一基质的白光。本文主要综述近几年Eu

Europium has been widely used in inorganic luminescent materials because of its excellent optical properties. The luminescence properties of the activator ions are determined by their valence state and are affected by the crystal structure of the matrix. Eu
2+
and Eu
3+
exhibit different optical properties
and it is possible to obtain a white light when two kinds of ion in a single matrix. In this review
research progress about luminescent properties of Eu
3+
-Eu
2+
coexisting in aluminate
phosphate
silicate and borate has been described
which was paid more attention at the present stage. In addition
the reduction condition of Eu
3+
to Eu
2+
and the mechanism have been summarized in this paper.
