| 摘 要： | 对不同温度和不同催化条件下用高温热解法制备的硼碳氮(BCN)纳米管的拉曼光谱进行了分析。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。不同催化剂对BCN纳米管的拉曼光谱也有影响，当以钴/二茂铁和镍/二茂铁为催化剂时的ID/IG值比以钴、镍和钴/镍为催化剂时大，说明这时的B、N的掺杂浓度较高，纳米管的质量较好，这与透射电子显微镜观察结果一致。

| Abstract: | Raman spectra of boron carbonitride (BCN) nanotubes made by thermal decomposition under different temperatures and with different catalysts were analyzed. 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. I(D)/I(G) is higher with cobalt/ferrocene and nickel/ferrocene than with cobalt, nickel and cobalt/nickel as catalysts. This means that better BCN nanotubes with B and N contents can be produced with the former. The results were confirmed by TEM observation. |
