在水合ＮａＹ、ＮａＸ和ＮａＡ中，Ｃｅ－ｏ键的共价程度依次递减，５ｄ能带随之上升，Ｃｅ￣（３＋）的５ｄ￣１→Ｆ＿Ｊ发射峰逐渐移向短波区，经焙烧处理后，在ＮａＸ和ＮａＡ中存在两种Ｃｅ￣（３＋）发射中心。两种中心受到的晶场作用不同，发射峰差别较大。ＮａＹ中只有一种Ｃｅ（３＋）发射中心。
In the hydrated NaY, NaX and NaA, the covalent degree of Ce-o bonds decreases in descending order and the energy band increases with the increase of 5d. The 5d ~ 1 → F_J emission peak of Ce¯ (3+) gradually shifts to the short wave zone. After roasting There are two Ce ~ (3+) emission centers in NaX and NaA. The two kinds of centers are affected by different crystal fields and have different emission peaks. There is only one Ce (3+) emission center in NaY.
