A hexagonal symmetric Au metasurface, made by polystyrene nanosphere lithography and metal coating, is developed to enhance the photoluminescence intensity of monolayer MoS2. By using nanospheres of different sizes, the localized surface plasmon resonances of the Au metasurfaces can be effectively tuned. By transferring monolayer MoS2 onto the Au metasurface, the photoluminescence signal of the monolayer MoS2 can be significantly enhanced up to 12-fold over a square-centimeter area. The simple, large-area, cost-effective fabrication technique could pave a new way for plasmon-enhanced light-mater interactions of atomically thin two-dimensional materials.This work was supported in part by National Natural Science Foundation of China (Grant No. 62075093 and 61805113), China Postdoctoral Science Foundation (2020M672697), Natural Science Foundation of Guangdong Province (Grant No. 2018A030310224 and 2019A1515110864), Guangdong Innovative and Entrepreneurial Research Team Program (Grant No. 2017ZT07C071), and Shenzhen Science and Technology Innovation Commission (Grant No. GJHZ201809281552 07206, JCYJ20170817111349280, and JCYJ2018030518063 5082).
