▎ 摘　　要

We report results from an investigation into the plasmonic properties of metallic nanoparticles supported by graphene fabricated using two different methods. In the first method we used electron- beam lithography to produce ordered arrays of metallic nanoparticles. In the second method we used a technique based on electrochemistry to produce random arrangements of metallic nanoparticles. Our results show that both pristine graphene and a more conducting intercalated variant are excellent substrates for plasmonic nanoparticles owing to their transparency and atomically thin nature, opening an interesting route for building plasmon- based bio- and chemical-sensors, and for developing transparent and flexible optoelectronics.
