Abstract
We show that strong photoluminescence (PL) can be induced in single-layer graphene using an oxygen plasma treatment. The PL is spatially uniform across the flakes and connected to elastic scattering spectra distinctly different from those of gapless pristine graphene. Oxygen plasma can be used to selectively convert the topmost layer when multilayer samples are treated.
摘要
我们证明了使用氧等离子体处理可以在单层石墨烯中诱导强的光致发光（PL）。PL 在薄片上具有空间均匀性，并且与无带隙原始石墨烯的弹性散射光谱明显不同。当处理多层样品时，氧等离子体可以用于选择性地转化最顶层。
