C30B 11/14 - Single-crystal-growth by normal freezing or freezing under temperature gradient, e.g. Bridgman- Stockbarger method characterised by the seed, e.g. its crystallographic orientation
The invention discloses a simple, scalable and convenient solvothermal method of obtaining fluoralkylated carbon quantum dots—Fluocar® Nano materials, by solvothermal pyrolysis of an organic substance in the presence of fluoroorganic substance that contain fluoroalkyl groups. The obtained material is water- and organic solvents soluble, grafted fluorine is hydrolytically stable, and obtained dots having intense luminescence in a wide range of wavelengths, from blue to NIR. Photoluminescent (PL) spectral map of obtained carbon dots solution is highly sensitive to pH changes and rare earth metal ions concentration in this solution. Also PL-map of such material is sensitive to organic complex moiety (e.g. Acidum salicylicum, and penicillinum).
Synthesized materials can find use as the classic and fluorescent dye replacement, as the carrier of biologically active substances, for bio-imaging, theranostic, for cytological studies, (photo)catalysis, as electrode component, as well as a sensor or biosensor, or for other uses.

A chemical vapor deposition method for fluorine-containing carbon materials preparation provided. The claimed method comprises treating of carbons with fluorocarbons or derivatives that passes at a moderate high temperature. The fluorine-containing carbon materials show hydrophobicity, high thermal stability and can be used as catalysts support, lithium battery anodes, and hydrophobic materials or as surface precursor. Surface fluorine characterized by intensive signal in the XPS spectrum, found in a range of 685-687 eV. Obtained fluoro-containing functionalities is stable at a temperature about 1000° C.
The authors propose to use Fluocar® name for materials synthesized using the claimed method.
