Abstract
Intensity parameters for the luminescence transitions between crystal‐field levels of the 4f6 configuration of Eu3+ in Y2O2S, LaOCl, LiYF4, Na5Eu(MoO4)4, and Na5Eu(WO4)4 are discussed. The superposition model is used to relate the parameters to parameters determined for other ions in both similar and different host crystals. The results confirm our earlier observations that mechanisms outside the point‐charge crystal‐field model are required in order to rationalize the signs of the intensity parameters for lanthanide ions in solids.Keywords
