In this paper, we report the preparation and spectroscopic properties of Yb²⁺-doped silica-based glass prepared by the solid state reaction using the oxyhydrogen flame fusing process. The glass exhibits broadband emission in the visible region due to a 5d-4f transition of the rare earth ions. The emission peak wavelength and bandwidth are especially 505 nm and 147 nm for Yb²⁺-doped silica-based glass at the room temperature. The color coordinate calculation shows that the Yb²⁺-doped silica-based glass has a better color coordinate (0.28, 0.37) in the white light region.
