Broadband emission at 2.7 µm is observed in an -doped --- glass. The measured emission band full-width-at-half-maximum (FWHM) is ∼184.4, approximately 36 nm wider than that of fluoride glasses. The 2.7 µm emission intensity is almost twice as strong as that of fluoride glasses. The peak values of emission and absorption cross-sections are calculated to be 1.54×10 and 1.19×10, respectively. This oxyfluoride heavy metal glass shows potential as broadband mid-infrared emission gain material.
