Abstract

This paper proposes a simple, direct, and fast method for the quantitative detection of oxygen in reduced graphene oxide (r-GO) by femtosecond laser-induced breakdown spectroscopy (fs-LIBS). First, GO was reduced by continuous-wave (CW) laser beams with different powers; subsequently, the oxygen content in the r-GO was detected through the intensity of oxygen obtained by fs-LIBS. The fit of the observed data and errors by LIBS was compared with the results of x-ray photoelectron spectroscopy (XPS), and the fs-LIBS results correlate well with the XPS results; it indicated that fs-LIBS can realize quantitative analysis of the GO-reduction degree. The method provides a convenient and time-efficient way for detecting the reduction degree of r-GO and can extend the applications of r-GO with different reduction degrees.
