Abstract

This work present optical proprieties of graphite oxide and thermally reduced graphite oxide for five different temperatures: 100, 125, 150, 175, 200 0C. Molecular absorption spectra of the carbon structures were obtained using Time-Domain Spectroscopy (THz-TDS) Kit from EKSPLA Company. Usable spectral range from 100 GHz to 5 THz with spectral resolution 50GHz. Results obtained in THz spectroscopy showed that the carbon structure with different concentrations of oxygen have unique molecular spectrum..
