拉曼光谱

站内搜索了下，发现讨论的高人挺多，可是还是有一些疑问：
石墨化碳的拉曼光谱是不是只在1580cm-1有一个峰？
而无定形碳只在1340cm-1有一个峰？
如果1340和1580处各有一个峰，是不是就代表所测碳材料部分石墨化？
看到一篇文章里面有这样一段描述，不是很明白
The Raman spectrum of the as-obtained
carbon microtubes is show in Figure 4, in which a broad peak
at 1334 cm-1 as well as a sharp absorption peak at 1600 cm-1
can be clearly seen. The peak at 1334 cm-1 is usually associated
with the vibrations of carbon atoms with dangling bonds for
the in-plane terminations of disordered graphite and is labeled
as the D-band, and the peak at 1600 cm-1 (G-band) (corresponding
to the E2g mode) is closely related to the vibration in
all sp2 bonded carbon atoms in a 2-dimensional hexagonal
lattice, such as in a graphene layer.26,27 The intensity ratio of
the D to G band (ID/IG) is calculated to be 0.64, further reflecting
the relative disorder and low graphitic crystallinity of the CMTs.

要分峰拟合，ID/IG是分峰拟合后两个峰的面积比，这个值越小，表示石墨化程度越高。

ID/IG越小,石墨化越低吧,D峰对应的是石墨团簇的尺寸大小

貌似只要是碳材料，都有G峰的

只要是碳材料，1580都有峰，即G峰
单晶石墨只在1580出峰
无序碳材料在1580和1340都有峰，文献看D峰相对于G峰的强度越高，石墨化程度越小

什么叫石墨化程度？ 谢谢

MM这个强度是面积还是峰高啊

我们的名字倒很像，就是你的这个公式记错了吧，G带越高，石墨化程度越高吧
