Abstract
Near infrared fluorescence was observed from single walled carbon nanotube–borosilicate glass composite around 0.84–2.03μm with 325nm laser excitation. Band gap fluorescence of SWCNT bundles along with defect related fluorescence from SiO2 structure were the source of the NIR emissions of the composite. The emission spectra was 1185nm wide that contains three main transmission windows for fiber optic telecommunications. The results strongly indicate high potentiality of this material in broadband fiber optic telecommunications and fabrication of NIR tunable lasers.
