7 to 8 mu m emission from Sm3+ doped selenide fibers

Abstract : We report on the observation of the long wave-infrared (LWIR) emission centered at 7.3 mu m of Sm3+ doped chalcogenide fibers. The chemical composition of the selenide glass host matrix (Ga5Ge20Sb10Se65) enables the drawing of 500 ppm and 1000 ppm Sm3+ doped fibers. By means of conventional glass elaboration methods, these Sm3+ doped fibered materials exhibit a significant emission band from 6.5 to 8.5 mu m with a maximum emission around 7.3 mu m whether they are excited at 1.45 mu m or at 2.05 mu m. Absorption spectra, Judd-Ofelt analysis, NIR, MWIR and LWIR luminescence spectra are presented and discussed.
