Электронные спектры ионов самария в расплавленных фторидах щелочных металлов

Abstract

Sperctral research of molten SmF3-MF (M=Li, Na, K, Cs) was performed. The samples were prepared using zone molten alkali fluorides. Absorption spectra were measured using samples with the same amount of SmF3. The behavior of hypersensitive and common f-f transition bands was described. Absorbtion bands correspond to f-f transitions in SmF6 3-groups. The composition of SmF6 3- group second coordination sphere depends on solvent alkali cation type.
