eng	Intense near-infrared and midinfrared luminescence from the Dy3+-doped GeSe2–Ga2Se3–MI, M=K, Cs, Ag… chalcohalide glasses at 1.32, 1.73, and 2.67 mm	The intense 1.32, 1.73, and 2.67 mu m near-infrared and midinfrared emissions were observed from the Dy(3+)-doped GeSe(2)-Ga(2)Se(3)-MI (M=K, Cs, Ag) chalcohalide glasses. These glasses are red light transparent therefore can be pumped by a semiconductor lasers operating at similar to 808 nm. The 2.67 mu m emission has not been reported yet which corresponds to an absorption minimum in fluoride fibers and can be very useful for long distance communications. The intensity of emissions is very sensitive to the local chemical environment of Dy(3+) ions embedded in these metal halide modified glasses. A plausible correspondence between the emission intensity and the average oscillator strength was found	RARE-EARTH IONS;LANTHANUM SULFIDE GLASS;JUDD-OFELT PARAMETERS;SB-SE GLASSES;OPTICAL-PROPERTIES;CHALCOGENIDE GLASSES;
