Here we designed a new kind of SERS substrate referred to as a MoS2-coated Cu nanopaticles (MoS2@CuNPs) substrate for R6G detection. The Cu nanoparticles wrapped by a thin MoS2 film were directly synthesized on flat quartz by two annealing process in a mixture of argon and hydrogen. Signals from a M...
