摘要 | The absorption spectra of Sm2+ doped in MFX (M=Sr, Ba; X=Cl, Br) crystals were studied within the range of 20,000-35,000 cm(-1) as a function of temperature and host The absorption bands observed were described with a simple model developed by Wood and Kaiser using group theory. The temperature and host dependence on the F-7(0)-> D-5(3) Fano resonance lines were investigated. BaFCl:Sm2+ system showed a "normal" F-7(0)-> D-5(3) transition at 4K in spite of similar crystal structure and absorption profile with other MFX hosts. New Fano resonances were observed in the absorption spectra at higher energies (23,000-25,000 cm(-1)) for all MFX:Sm2+ systems at 4 K which persist up to room temperature. Preliminary energy level calculation showed that these resonance lines involve the interaction between higher excited L-5(J) states of 4f(6) configuration and 4f(5)5d(1) configuration.
