Effect of spatial restriction on the photoluminescent properties of carbon nanomaterials

Photoluminescent (PL) properties of carbon-based nanomaterials obtained on the base of sodium dextran sulfate (DS) were compared. DS water solution, dry powder and co-precipitated inside pores of CaCO 3 microparticles solution were thermally treated and clear difference between these materials was found. Effect of spatial restriction of CaCO 3 pores showed itself in the identity of PL properties for material, obtained by thermal and hydrothermal treatment; in the absence of CaCO 3 microparticles the PL spectra were quite different.
