The impacts of wrinkles on enhanced photoluminescence (PL) and optoelectronic performance are systematically investigated by experiments and simulations. High-resolution transmission electron microscopy (HRTEM) and Raman spectroscopy results indicate that the wrinkled 2D MoS<sub>2</sub> is subjected to a compressive strain (layer space decreases from 6.2 to 6.1 Å), alongside a redshift in the Raman signals. The PL intensity of wrinkled 2D MoS<sub>2</sub> shows a significant enhancement of up to 133% at the strain of 1.683%. Furthermore, the PL results suggest that the wrinkles can effectively adjust the bandgap (30 meV/%).
