您要查找的是不是：
- 隨著(zhù)制備溫度的升高 ,拉曼光譜中D帶和G帶的強度比ID/IG 由小變大 ,而后又變小 ,說(shuō)明存在一個(gè)最佳溫度 ,在該溫度下生成的BCN納米管中B、N元素摻雜濃度最大。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.
