您好!
这两天花费一些功夫找到一些参数,希望有用。
1. 我的样品是多壁碳纳米管,用硫酸和硝酸按照一定比例处理的。
2. 我做拉曼的参数如下:

3. 参考文献中图的参数:
The Raman spectra were collected on a Renishaw Raman spectrometer using 514 nm laser.
文章中关于拉曼的描写:As shown in Figure S6, a D-band located around 1342 cm-1 and a G-band around 1570 cm-1 were observed. The higher order peak appeared at 2670 cm -1 and a small broad peak at 2910 cm-1 can be assigned to a combination of D+D and D+G bands, respectively. The G band arises from the bond stretching of all sp2-bonded pairs, including C-C, B-C, N-C, and B-N, while the D-band is associated with the sp3 defect sites.
