Abstract :
By injecting ethanol molecules into the argon plasma environment graphene sheets can be produced [1]. From this motivation the atmospheric pressure 2.45 GHz microwave plasma source was built. The argon and helium discharges with ethanol were obtained in a quartz tube which placed in a rectangular cavity. The discharge environment will be analyzed by optical emission method. The synthesized graphene sheets will be analyzed by scanning electron microscopy, x-ray diffraction method and Raman spectroscopy. The plasma power, gas flow rate and temperature effect on graphene sheets will be given.
