ABSTRACT
Broadband near-infrared emission from Ni2+ in zinc-alumino-silicate glass was observed at room temperature. The emission band had a peak at ∼1400 nm with a bandwidth more than 300 nm, and covered the O, E, S, C, and L bands (1260-1625 nm). The emission lifetime was more than 200 µs even at room temperature. The observed near-infrared emission could be attributed to the ³A2g(³F)→³ T1g(³F) transition of Ni2+ in octahedral sites. This nickel-doped glass can be expected as an amplification medium for tunable lasers and broadband optical amplifiers for the wavelength division multiplexing transmission system applications.
