摘要

•Germanate glasses containing Sn2+ exhibit broadband emissions with FWHM up to 142 nm.•Full-visible-spectrum white light emissions are observed in Sn2+/Mn2+ co-doped germanate glasses.•A w-LED with Ra up to 95.3 is assembled based on Sn2+/Mn2+ co-doped germanate glasses and 310 nm chip.•Assembled w-LED delivers warm white light with 3811 K, which is similar to that of sunlight.
