Paper Abstract

Samples of disordered carbon obtained by different technologies (carbon plasma deposition, irradiation, anodic etching etc.) by Raman scattering (RS) and photoluminescence (PL) were studied. The common spectral features for these cardinally different technologies preparation samples are found. The following conclusion from the obtained data are made: • In some samples of disordered carbon there are carbon nanoparticles, which consist of a core containing sp2 bonds and a shell containing sp3 bonds. Vibrations states of these bonds interact with each other. These nanoparticles have a strong photoluminescence in visible range of a spectrum; • On a surface of disordered carbon there can be metastable structural formations as the torn off chains. Lifetime of such structures is approximately half-year. Such structures most frequently arise on the irradiated surface.
