Abstract: Raman scattering and luminescence have been observed in coal. The similarity of our results to those of disordered graphite is striking. The disorder-induced line in graphite is shown to be due to the high phonon density of states at 0 and K points of the Brillouin zone for graphite. The luminescence shows spectra having anti-stoke parts indicating the presence of multi-step processes. The Raman spectra are not affected significantly by the mineral matter contents in coal, thus our observations offer a new approach for the study of the microstructure of coal. © 1977.
