摘　　要：Ytterbium-doped yttrium oxysulfide （Yb：Y2O2S） has been synthesized by solid-state reaction with sulfide flux. Diffuse reflection and emission spectra have been measured in order to determine the crystal field splitting of Yb^3＋ ion in the YOS lattice. According to the crystal-field levels probed in the spectra, the crystal field splitting of 2F7/2 manifold of Yb^3＋ ion in YOS is 709 cm^-1, which is large enough for the quasi-three-level laser operation of Yb^3＋ ion. Emission peak position, width, full-width at half maximum （FWHM）, and normalized intensity of Yb：YOS are fitted from its emission spectrum. For comparison, relevant data of 5.4 at.-% Yb：YAG is also provided.Ytterbium-doped yttrium oxysulfide （Yb：Y2O2S） has been synthesized by solid-state reaction with sulfide flux.
