Ultraviolet and near-infrared Raman spectroscopy of graphitic C3N4 ...
2009年4月6日 · Here, we report measurements of the Raman spectra of graphitic g -C 3 N 4 phase, using deep ultraviolet (UV, 244 nm) and near-infrared (NIR, 785 nm) light for excitation of Raman scattering. It is demonstrated that the UV and NIR Raman spectra of g -C 3 N 4 phases are substantially different from those measured with visible Raman spectroscopy.

石墨C 3 N 4 相的紫外和近红外拉曼光谱,Chemical Physics Letters
在这里,我们报告了石墨g -C 3 N 4相的拉曼光谱的测量结果,使用深紫外光(UV,244 nm)和近红外光(NIR,785 nm)激发拉曼散射。 结果表明,g -C 3 N 4相的UV和NIR拉曼光谱与用可见拉曼光谱法测得的光谱有很大不同。 用可见拉曼光谱法获得的g -C 3 N 4相的典型拉曼光谱在1357和1560 cm -1处显示两个主要的重叠谱带。 相反,g -C 3 N的紫外和近红外拉曼光谱4相在691和988 cm -1附近表现出两个强峰。 这些峰被暂时分配给不同类型的s-三嗪环呼吸模式。 g -C 3 N 4相 …
