Abstract
Upon 808 nm excitation, an intense broadband near-infrared emission from has been observed in chalcogenide glass-ceramics (GCs) containing nanocrystals. The emission band peaking at 1250 nm covers the O, E, S bands (1000–1500 nm). The formation of nanocrystals () increases the emission intensity of by more than three times. The quantum efficiency of the present GCs is as great as 36% at room temperature.
