Long wavelength emissions of periodic yard-glass shaped boron nitride nanotubes
Extraordinary and stable long wavelength emission centered at 685 nm from the yard-glass
shaped boron nitride nanotubes YG-BNNTs was observed in their cathodoluminescence and
photoluminescence spectroscopy. The mechanism for this near-red light emission at 685 nm is
attributed to the periodical nature of the BNNT units with regular lattice defects. The visible-light
emission from YG-BNNTs indicates that this material has great potential for applications as
nano-optical and/or nano-optoelectronic devices in nanoscale surgery and spectroscopy.
