Bi-doped materials have received great interest at home and abroad since 2001,owing to their ultra broad IR luminescence properties in the wavelength region from 1000 to 1700 nm with a FWHM up to about 300 nm.The bismuth-doped glass has the potential to become the next great wide-band optical amplifier.To our knowledge,in most Bi-doped materials,bismuth was introduced as dopant of a small amount lower than 5 mol%.
