ENERGY LEVEL SHIFTS AND NEPHELAUXETIC EFFECT OF RARE EARTHS IN SOLID
固体中稀土离子的能级位移和电子云扩大效应

In this paper, the shifts of 5DJ and 7FJ energy levels of Eu3+ ion caused by crystal field effect, are calculated in 25 hosts containing Eu3+ ions. The relation between the calculated shifts and experimental values are analysed. The correct order on nephelauxetic effect shifts in these hosts is given.
