由不同的二维材料构成的货车德瓦尔斯（vdWs）异质结构由于其独特的光学和电学性质而受到广泛的关注。本文采用化学气相沉积法和湿法转移法成功制备了MoS 2/h-BN、MoS 2/graphene、WS 2/h-BN和WS 2/graphene vdWs异质结构。利用光学显微镜和拉曼光谱仪分别观察和测试了上述异质结构样品的分布、拉曼光谱和光致发光（PL）光谱，可用于研究其生长机理和光学性质。同时，利用拉曼光谱和光致发光谱也可以分析异质结构薄膜的均匀性和成分分布。通过对2D-2D vdWs异质结构材料的结区和非结区的PL谱和拉曼谱的对比分析，可以解释拉曼谱和PL谱变化的内在机理，并分析激光功率对异质结构材料光学性质的影响。这些异质结构材料在叠层或结处表现出新颖独特的光学特性，可为制备合适的性能优异的TMD异质结构材料提供可靠的实验依据。
Due to the attractive optical and electrical properties, van der Waals (vdWs) heterostructures constructed from the different two-dimensional materials have received widespread attention. Here, MoS2/h-BN, MoS2/graphene, WS2/h-BN, and WS2/graphene vdWs heterostructures are successfully prepared by the CVD and wet transfer methods. The distribution, Raman and photoluminescence (PL) spectra of the above prepared heterostructure samples can be respectively observed and tested by optical microscopy and Raman spectrometry, which can be used to study their growth mechanisms and optical properties. Meanwhile, the uniformity and composition distribution of heterostructure films can also be analyzed by the Raman and PL spectra. The internal mechanism of Raman and PL spectral changes can be explained by comparing and analyzing the PL and Raman spectra of the junction and non-junction regions between 2D-2D vdWs heterostructure materials, and the effect of laser power on the optical properties of heterostructure materials can also be analyzed. These heterostructure materials exhibit novel and unique optical characteristics at the stacking or junction, which can provide a reliable experimental basis for the preparation of suitable TMDs heterostructure materials with excellent performance.
