MoS2 and ZnS are considered two promising wide-bandgap materials; hence, the fabrication of ZnS/MoS2 heterostructures is interesting. Herein, ZnS/MoS2 heterostructures were successfully synthesized by a simple 2-step hydrothermal method. SEM and energy-dispersed spectroscopy (EDS) provided insights into the morphology and elemental composition of the synthesized heterostructures while XRD spectra analysis further elucidated their crystal phases. Excitingly, photoluminescence (PL) spectroscopy showcased a broad emission band spanning from 400 to 700 nm, underscoring the tremendous potential of this material. Additionally, photoluminescence excitation (PLE) spectroscopy unveiled a robust broadband peaking at 278 nm, accompanied by a weaker band peaking at 370 nm, suggesting the possibility of utilizing NUV light as a pumping source. These findings highlight the exciting prospects of ZnS/MoS2 heterostructures and underscore their versatility in advancing lighting technology toward more efficient and vibrant illumination.
