PPT-A new fluorescence quenching microscopy technique has been

Ozkans laboratory in UCRiverside to perform defect analysis and surface metrology of largearea CVDgraphene sheets This method utilizes the quenching of fluorescence from dye molecules by graphene via resonant energy transfer to increase the visibility of graphene on a glass substrate A largearea fluorescence montage image of the dyed graphene sample is collected and processed to identify the graphene and indicate the graphene layer thickness throughout the entire graphene sheet Furthermore chemically functionalized doped with fluorine parts of graphene film is visualized using the same technique The emission of the dye is quenched to a different extent by fluorinated and pristine graphene which provides the fluorescenceimaging contrast essential for this method The regions with pristine graphene appear darker on the fluorescence images than the regions with fluorinated graphene enabling largescale mapping of the functionalized regions in CVD grown graphene sheets Complex circular patterned regions of doped and pristine graphene regions are resolved with great accuracy This method is posed for widespread adoption by graphene manufacturers as a basis for facile and high throughput metrology of large scale graphene sheets Finally this work featured as cover articles in .
