Abstract
Efficient multicoloured electroluminescence in MIS structures fabricated on conducting CdF2 crystals doped with rare earth impurities (Pr, Sm, Eu, Gd, Tb, Dy, Ho, Er, Tm) is reported. A high-field impact excitation of RE centres is shown to be the most effective for the cubic symmetry centres. This phenomenon and differences in EL efficiency between RE impurities is discussed.Keywords
