您要查找的是不是：
- 随着制备温度的升高 ,拉曼光谱中D带和G带的强度比ID/IG 由小变大 ,而后又变小 ,说明存在一个最佳温度 ,在该温度下生成的BCN纳米管中B、N元素掺杂浓度最大。The intensity ratio of D to G band, ?I D/I G?, increases and then decreases with the increase of the temperature. It was indicated that there exists an optimal temperature under which B and N incorporation is maximum. The catalysts influence also the Raman spectra of the BCN nanotubes.
