contents	Research of the nonlinear optical characteristics of transition metal dichalcogenides in the presence of photoactive particles, plasmonic nanocavities, waveguides, and metamaterials is still in its early stages. This investigation delves into the high-order harmonic generation (HHG) from laser induced plasma of MoS2 nanosheets in the presence of semiconductor photoactive medium such as CdSe and CdSe/V2O5 core/shell quantum dots. Our comprehensive findings shed light on the counteractive coupling impact of both bare and passivated quantum dots on MoS2 nanosheets, as evidenced by the emission of higher-order harmonics. Significantly, the intensity of harmonics and their cut-off were notably enhanced in the MoS2-CdSe and MoS2-V-CdSe configurations compared to pristine MoS2 nanosheets. These advancements hold promise for applications requiring the emission of coherent short-wavelength radiation.
