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 WTe2 and NiTe2. The study found that the enhancement effect of WTe2 depends on the environment, and NiTe2 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.
