Study of the Vibrational States of Nanocrystalline Carbon by Diffuse Reflection Spectroscopy

摘要

The possibility of performing a quantitative analysis of vibrational states of nanocrystalline carbonhas been explored by using the spectroscopic method of diffuse IR reflection. An expression derived from the Kubelka-Munk relation has been proposed and employed to investigate the effect of the original parameters of a sample (absorber concentration, sample dispersion, radiation frequency, scattering factors) on the characteristic features of IR spectra. The IR absorption bands observed in the diffuse reflection spectrum of pyrographite were assigned.
