dc.description.abstract | Nitrogen (N) was doped into graphene oxide (GO) films at temperatures of 600-900 degrees C under the flow of a mixture of NH3 and Ar. The N (atomic) concentration was varied in the range of 3.63-7.45%. XPS and FTIR spectra show that there are mainly single C-N and double C=N bonds in the GO sheet. Raman spectra indicate that the G band becomes closer to the position of the G band of graphite with increasing doping temperature, and thus reveal that N doping produces a blue-shift of the G-band. In room-temperature photoluminescence (PL) spectra, N-doping produces an increase not only in the overall PL intensity, but also in the wavelength of the peak maxima. The shift of the induced PL of N-doped graphene is attributed mainly to the increased number of graphitic (or quaternary) N. (c) 2012 Elsevier Ltd. All rights reserved. | en_US |
