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 µm of Sm doped chalcogenide fibers. The chemical composition of the selenide glass host matrix (GaGeSbSe) enables the drawing of 500 ppm and 1000 ppm Sm doped fibers. By means of conventional glass elaboration methods, these Sm doped fibered materials exhibit a significant emission band from 6.5 to 8.5 µm with a maximum emission around 7.3 µm whether they are excited at 1.45 µm or at 2.05 µm. Absorption spectra, Judd-Ofelt analysis, NIR, MWIR and LWIR luminescence spectra are presented and discussed.
