摘要：
Optical spectra of MF-GdF3 (M = Li, Na, K, and Cs) and NaF-CsF-GdF3 molten systems are presented. On the basis of spectral data, it has been determined that stable complex groups GdF63- are formed in these melts. In the molten LiF-GdF3 system, the GdF4- group, which decomposes over time, is found along with the GdF63- complex group. It has been suggested that the number of cations in the second coordination sphere of the GdF63- groups decreases from 14 to 13 when passing from the melts of LiF, NaF to KF, CsF.
