Effective growth of multiwalled boron nitride nanotubes (BNNTs) has been obtained by thermal chemical vapor deposition (CVD). This is achieved by a growth vapor trapping approach as guided by the theory of nucleation. Our results enable the growth of BNNTs in a conventional horizontal tube furnace within an hour at 1200 °C. We found that these BNNTs have an absorption band edge of 5.9 eV, approaching that of single h-BN crystals, which are promising for future nanoscale deep-UV light emitting devices.
通过热化学气相沉积（CVD）已实现了多壁氮化硼纳米管（BNNTs）的有效生长。这是通过成核理论指导的生长气相捕获方法实现的。我们的结果使得能够在传统的卧式管式炉中于1200°C下在一小时内生长BNNTs。我们发现这些BNNTs的吸收带边缘为5.9 eV，接近单h-BN晶体的吸收带边缘，这对于未来的纳米级深紫外发光器件很有前景。
