描述了还原氧化石墨烯薄膜的沉积及其光电性能。用真空过滤法制备了厚度为1 ~ 10nm的薄膜。通过改变氧化石墨烯水悬浮液的过滤体积，薄膜的导电性可以改变6个数量级，同时保持60%-95%的透光率。此外，还证实了Cl掺杂对电导的增强作用。还原和氯化处理的结合使还原的氧化石墨烯薄膜具有足够的导电性，可以将其作为概念验证有机光伏器件的空穴收集电极。(C) 2008年美国物理研究所。
The deposition and optoelectronic properties of reduced graphene oxide thin films are described. Thin films with thicknesses ranging from 1-10 nm have been deposited by the vacuum filtration method. The conductivity of the thin films can be varied over six orders of magnitude by varying the filtration volume of the graphene oxide aqueous suspension while maintaining the transmittance between 60%-95%. In addition, enhancement in the conductance through Cl doping is demonstrated. The combination of the reduction and Cl treatments make the reduced graphene oxide thin films sufficiently conducting to incorporate them as the hole collecting electrode in proof of concept organic photovoltaic devices.
