Boron nitride (BN) nanorings were synthesized using a sulfur vapor assisted solid-state method at 600 degrees C. The rings had typical diameters of 100-300 nm, and the shells were 5-20 nm thick and about 50 nm wide. On the basis of the characterization of X-ray powder diffraction pattern (XRD), X-ray photoelectron spectroscopy (XPS), and Fourier transformation infrared spectroscopy (FTIR) measurement, the as-prepared product was pure-phase hexagonal BN. High-resolution transmission electron microscopy (HRTEM) images proved that the nanorings were formed through the coiling of the (002) planes of hexagonal BN. A possible growth process for BN nanorings is suggested.
采用硫蒸气辅助固态法在600℃合成了氮化硼（BN）纳米环。这些环的典型直径为100 - 300nm，壳层厚度为5 - 20nm，宽度约为50nm。基于X射线粉末衍射图谱（XRD）、X射线光电子能谱（XPS）和傅里叶变换红外光谱（FTIR）测量的表征，所制备的产物为纯相六方BN。高分辨率透射电子显微镜（HRTEM）图像证明纳米环是通过六方BN（002）面的卷曲形成的。提出了BN纳米环可能的生长过程。
