N2 - We report on ultrabroad infrared (IR) luminescences covering the 1000-1700-nm wavelength region, from Bi-doped 75GeO2-20 RO-5Al2O3-1Bi2O3 (R = Sr, Ca, and Mg) glasses. The full width at half-maximum of the IR luminescences excited at 980 nm increases (315 → 440 → 510 nm) with the change of alkaline earth metal (Mg2+ → Ca2+ → Sr2+). The fluorescence lifetime of the glass samples is 1725, 157, and 264 μs when R is Sr, Ca, and Mg, respectively. These materials may be promising candidates for broad-band fiber amplifiers and tunable laser resources.
