The FTIR peak centered at 1489cm-1 appears to indicate the high quality BNNTs. The band gap of these multi-wall bamboo BNNTs drawn from Photoluminescence spectrum is 5.75 eV, just slightly narrower than the hexagonal BN (h-BN) powder (5.82 eV). And the BNNTs present stronger and broader UV-visible-NIR light emission in comparison with h-BN powder.Keywords: Absorption; Annealing; Ball milling; Boron; Boron nitride; Fourier transform infrared spectroscopy; Nanopores; Nanoscience; Nanostructures; Nanotechnology; Nanotubes; Nitrides; Nonmetals; Optical properties; Photoexcitation; Semiconducting cadmium telluri And ball milling; Band gap; BN nanotube; Component: FTIR; Optial absorbtion; Optical excitation200610.1109/ICONN.2006.3405512015-12-07
