Abstract

We have shown that efficient superbroadband near-IR luminescence can be realized in bismuth-doped high-silica nanocrystalline zeolites. The emission band covered the range of 930–1620 nm, with a maximum peak at 1146.3 nm , an FWHM of 152 nm , and a lifetime of over 300 μ s under the excitation of a 488 nm laser line. The observed luminescence was attributed to subvalent Bi ( Bi + ) ions formed in the annealed zeolites. These Bi-doped nanozeolites may find applications as superbroadband near-IR nano-optical sources.
