在室温下首次观察到碳纳米管的四级拉曼光谱，并且发现碳纳米管的Ｄ峰和Ｄ＊峰的斯托克斯线和反斯托克斯线频率不一致。此外，还发现碳纳米管的拉曼特征峰频率严重依赖样品的温度，随着温度增加，碳纳米管拉曼特征峰频率下移，频移与温度变化成线性关系。 The fourth-order Raman spectra of carbon nanotubes were observed for the first time at room temperature, and the Stokes and anti-Stokes line frequencies of the D and D * peaks of the carbon nanotubes were found to be inconsistent. In addition, it is also found that the Raman peak frequency of carbon nanotubes is heavily dependent on the temperature of the sample. As the temperature increases, the Raman peak frequency of the carbon nanotubes shifts downward. The frequency shift is linear with the temperature change.
