Synthesis and characterization of bamboo-like turbostratic boron nitride tubes

The bamboo-like turbostratic boron nitride (tBN) tubes were synthesized by chemical vapor deposition method. The as-prepared tBN tubes were characterized by X-ray diffraction, field emission scanning electron microscope (FESEM), field emission transmission electron microscope, Fourier transformed infrared spectrum, ultraviolet–visible (UV–vis) spectrum and photoluminescence (PL) spectrum. UV–vis spectrum revealed that the product had one broad band gap (4.5–4.7 eV) and PL spectrum showed that it had a visible emission at 457 nm (λex = 230 nm).
