Abstract

The Raman spectra of multiwall (bamboo-type) carbon nanotubes implanted with nitrogen have been investigated under excitation by different lasers with wavelengths λ = 405, 532, 633, and 785 nm in a wide frequency range from 50 to 4500 cm^–1. The spectra included intense bands corresponding to the G and D modes and their overtone transitions. The microscopic mechanism of the frequency shift of the D band of carbon nanotube Raman scattering with a change in the excitation wavelength is analyzed.

注入氮的碳纳米管的拉曼散射

摘要

在50至4500 cm ^–1的宽频率范围内，在波长为λ= 405、532、633和785 nm的不同激光激发下，研究了注入氮的多壁（竹型）碳纳米管的拉曼光谱。光谱包括对应于G和D模式及其泛音跃迁的强带。分析了碳纳米管拉曼散射D带的频移随激发波长的变化的微观机理。
