Bismuth glass
Webglass, these materials had been widely studied since then. In 2001, Fujimoto et al. [4] reported the NIR luminescence characteristics in bismuth-doped aluminosili-cate glass. They reported that 500-nm pumped light can produce a luminescence at 1000–1600 nm with the half-peak width (FWHM) of 200 nm and the lifetime of 630 µs at a peak of 1140 nm.
