Abstract: In this paper, we have investigated Sm3+→Sm/2+ valence transform in process ofpreparing KMgF3: Sm by high temperature decomposition of SmF3.We have also investi-gated the effect of host structure on the stability of Sm2+ in some complex fluorides and alka-line earth metal fluorohalogenides.

Key words: samarium, valence, complex halide, spectrum
