【 摘 要 】

The spray pyrolysis technique (SPT) is one of the most useful and simple methods to grow graphene oxide (GO) thin film. Good-quality GO thin films were fabricated by spray coating with GO powder (prepared by the modified Hummers method) on glass substrates. Raman spectroscopy, Field Emission Scanning Electron Microscope (FESEM), X-ray diffraction (XRD) analysis, and UV-visible spectroscopy were done to observe the presence of functional groups in the growth thin films and to determine the structure of GO. From the result of XRD test, the GO demonstrates peak at 10.58°(2θ), while the Raman spectroscopy reveals the presence of two prominent peaks, known as D and G bands, as well as 2D band. The ID/IG ratio for spray-deposited GO film was calculated with the value of 0.84. FESEM images showed that the glass substrates were completely covered by GO at different magnifications with a sheet-like structure. The optical absorption of graphene oxide was also observed at a wavelength rang of 275-350 nm.
