摘      要：Monolayer transition-metal dichalcogenides（TMDs） have attracted a lot of attention for their applications in optics and *** disulfide（MoS2）,as one of those important materials,has been widely investigated due to its direct band gap and photoluminescence（PL） in visible *** to the fact that the monolayer MoS2 suffers low light absorption and emission,surface plasmon polaritons（SPPs） are used to enhance both the excitation and emission ***,we demonstrate that the PL of MoS2 sandwiched between 200-nm-diameter gold nanoparticle（Au NP） and 150-nm-thick gold film is improved by more than 4 times compared with bare MoS2 *** study shows that gap plasmons can possess more optical and optoelectronic applications incorporating with many other emerging two-dimensional materials.
