High-Throughput Imaging of Graphene Based Sheets by Fluorescence Quenching Microscopy and Applications of Same

摘要

A method for imaging a graphene-based film. In one embodiment, the method includes the steps of providing a graphene-based film on a surface of a medium; forming a fluorescent coating over the graphene-based film to form a sample; illuminating the sample with light of a specific wavelength or wavelengths, which is absorbed by the fluorescent coating to cause the fluorescent coating to emit light of wavelengths longer than that of the absorbed light, which is quenched by the graphene-based film such that a visibility contrast is formed between the graphene-based film and the fluorescent coating; and imaging the graphene-based film from the visibility contrast.
