Surface Modification of Detonation Nanodiamond with Ethylenediamine and Hexamethylenediamine

The surface of chlorinated and fluorinated nanodiamond obtained by detonation synthesis was modified with ethylenediamine and hexamethylenediamine. Nanodiamonds with grafted diamines were found to manifest photoluminescence in Raman spectra; the occurrence and intensity of luminescence depended on the chemical nature of the diamines.
