SENSITIVE ELEMENT OF LUMINESCENT SENSOR BASED ON QUANTUM DOTS AND GRAPHENE AND METHOD FOR PRODUCTION THEREOF Russian patent published in 2021 - IPC G01N21/64 

FIELD: testing.

SUBSTANCE: invention relates to a sensitive element of a luminescent sensor used for optical detection of molecular bromine and bromine-containing substances in gaseous and liquid media, containing a dielectric substrate including a measuring interdigital electrode system, with a graphene layer, a quantum dot layer, including a core based on cadmium selenide and semiconductor shells based on cadmium selenide and zinc sulfide, and a layer of porous non-polar copolymer based on tetrafluoroethylene and vinylidene fluoride applied thereto. The invention also relates to a method for production thereof.

EFFECT: technical result of the present invention consists in the fact that the produced sensitive element of a luminescent sensor should exhibit a high sensitivity for detection of a particular determined compound, while being usable not only in gaseous but also in liquid media, primarily in aqueous and aqueous-alcoholic solutions.
