In this work, Ag/MoS₂ composite thin films were fabricated. The effects of MoS₂ layer on the structure and optical properties of Ag thin film were investigated. XRD results show that MoS₂ buffer layer has the effects of promoting grain growth of Ag and increasing their particle sizes confirmed by SEM images. The surface plasmon resonance (SPR) wavelength of Ag was observed to shift from 432 nm to 1650 nm with the introduction of MoS₂ buffer layer. The nonlinear absorption (NLA) response of Ag/MoS₂ composite thin films was significantly improved compared with that of the Ag single layer, which is attributed to the SPR of the Ag/MoS₂ composite thin films and the enhanced electric field induced by SPR. Moreover, the simulation results of Finite-Difference Time-Domain (FDTD) are in good agreement with the experimental results.

在这项工作中，制作了Ag / MoS ₂复合薄膜。研究了MoS ₂层对Ag薄膜的结构和光学性能的影响。XRD结果表明，MoS ₂缓冲层具有促进Ag晶粒生长和增加其粒径的作用，这由SEM图像证实。通过引入MoS ₂缓冲层，可以观察到Ag的表面等离子体共振（SPR）波长从432 nm转变为1650 nm 。与Ag单层相比，Ag / MoS ₂复合薄膜的非线性吸收（NLA）响应得到了显着改善，这归因于Ag / MoS ₂的SPR复合薄膜和SPR诱导的增强电场。此外，有限差分时域（FDTD）的仿真结果与实验结果吻合良好。
