XPS測(cè)定石墨烯問題
|
| 用光還原氧化石墨烯,審稿人提出這樣一個(gè)問題“How was the charging effect exactly removed from the XPS spectra “the charging shift was corrected by the binding energy of C1s at 284.6 eV” is a bit confusing for me. I guess that the authors meant that the effect of sample charging on the position of the C1s envelope was removed by shifting the main peak at the low binding energy side to 284.6 eV, which corresponds to the binding energy of 1s electrons in graphite.”我不懂呀,我就是按照其他文獻(xiàn)那樣測(cè)的XPS,光照前給個(gè)C1s譜,光照后給個(gè)C1s譜,然后分峰對(duì)照各含氧碳的比例。這個(gè)charging effect是什么東西?審稿人高低說的是什么?哪位大俠幫忙解釋一下。 |
