METHOD OF OBTAINING LUMINESCENT NANOPARTICLES OF CADMIUM SULPHIDE, STABILISED WITH POLYMER MATRICES Russian patent published in 2009 - IPC C09K11/54 C09K11/02 

FIELD: chemistry.

SUBSTANCE: method is described for obtaining luminescent nanoparticles of cadmium sulphide, stabilised with polymer matrices, involving growing nanoparticles of cadmium sulphide directly in polymer matrices. A polymer compound, chosen from a series which includes polystyrene-block-polyethylene oxide, polystyrene-block-polyethylene oxide, polystyrene-block-4-vinylpyridine or polyphenylene, is dissolved, anionic surfactant is added to the obtained mixture with subsequent addition of a compound which contains cadmium cations, and then a compound which contains sulphur anions, and after growing cadmium sulphide nanoparticles excess anionic surfactant is removed.

EFFECT: higher quality of luminescent cadmium sulphide nanoparticles, stabilised with polymer matrices, including brightness of light due to controlled process of growing nanoparticles and reduction of their agglomeration.
