▎ 摘　　要

We present the fabrication of graphene by chemical vapour deposition (CVD) on nickel foils. The growth process was optimized for formation of large area and high quality graphene monolayer films. The film quality was confirmed by Raman spectroscopy. Although the absorbance of a bare single graphene layer is limited to 2.3%, we show theoretically that it can be enhanced to 50% by integration with a resonant reflective membrane based on one-dimensional (1D) photonic crystal (PC) slab. The absorbance of a graphene monolayer combined with a PC membrane slab was increased up to 16%, experimentally. (C) 2012 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim
