摘要：

Lithium yittrium/lanthanum borate glasses doped with Sm ion were prepared by melt quenching technique. Both glasses were studied comparatively in Sm ion local environment and its effect to luminescence properties. XANES indicated that Sm ions in both glasses act as Sm3+ similar as original in Sm2O3 powder. EXFAS result showed that Sm3+ in both glasses are surrounded with first shell neighbor by six particles of oxygen. Sm-O distance and its fluctuation value in LiYBSm is larger than in LiLaSm glass. Latter value represents more asymmetric environment around Sm3+ in LiYB than in LiLaB system. This lead to better ability of absorption and emission in LiYBSm glass which appear in the spectra. The first and second strongest emission of both glasses belong to photon with 600 and 646 nm, via 403 excitation wavelength. From J-O analysis, LiYBSm glass performs more potential than LiLaSm, for using as lasing medium in high power laser with 600 nm and low-energy consumption laser with 646 nm. (C) 2017 The Authors.
