Abstract
The Finback–Warren method is used to determine the quantitative characteristics of the short-range order of thermally modified shungite carbon. The results of spectroscopic studies in the visible spectral region of “shungite carbon–optically active silicon or carbon nanoparticles” compositions are presented. It is shown that shungite samples with nanoparticles encapsulated in pores have photoluminescence activity in the visible region of the spectrum. Stable passivation of the surface of nanoparticles in the shungite matrix pores is observed.
