石墨烯发现以来,国内外掀起了对二维材料的研究热潮,二维材料的拉曼增强效应也备受关注。本实验以酞菁铜为探针分子,研究了WTe 2和NiTe 2的表面增强拉曼光谱。研究发现,WTe 2的增强效果取决于环境,NiTe 2则显示了增强效果与材料厚度的关系。同时,研究表明,拉曼光谱作为一种无损分析技术,对于研究探针分子、二维材料以及光电材料和器件的拉曼增强效应具有重要意义。
Since the discovery of graphene, there has been an upsurge in domestic and international research into two-dimensional materials, and the Raman enhancement effect of two-dimensional materials has also attracted much attention. In this experiment, copper phthalocyanine was used as a probe molecule to study the surface-enhanced Raman spectroscopy of WTe 2 and NiTe 2. The study found that the enhancement effect of WTe 2 depends on the environment, and NiTe 2 shows the relationship between the enhancement effect and the thickness of the material. At the same time, research shows that Raman spectroscopy, as a nondestructive analysis technology, is of great significance for studying the Raman enhancement effect of probe molecules, two-dimensional materials, and optoelectronic materials and devices.
