Highly oxidized graphene with enhanced fluorescence and its direct fluorescence visualization
We prepared hyper-oxidized graphene （HOG） as a form of graphene derivative by additional oxidation of graphene oxide （GO） sheets. HOG, which formed more functional groups and isolated conjugated clusters on the sheets, accordingly showed high solubility in water and alcohols, high transmittance and...

| description | We prepared hyper-oxidized graphene （HOG） as a form of graphene derivative by additional oxidation of graphene oxide （GO） sheets. HOG, which formed more functional groups and isolated conjugated clusters on the sheets, accordingly showed high solubility in water and alcohols, high transmittance and film transparence, longer fluorescence decay constant time, and en- hanced fluorescence in states of solution and solid. By contrast, GO has much weaker fluorescence in solution and its fluores- cence is totally quenched in solid. The influences of concentration, metallic ions, and pH on HOG fluorescence in aqueous so- lution were also investigated in detail. Due to HOG＇s strong fluorescence, direct visualization was realized on substrates and in solution. In addition, direct 3D fluorescence visualizations of HOG phase in polymer composites were achieved. These results show the great potential of HOG in a broad range of applications, from biological labeling, probes, and drug carriers to high- performance composites and nanomanipulation. |
