ELECTRROLUMINESCENT POLYMERIC NANOCOMPOSITE MATERIAL Russian patent published in 2005 - IPC

FIELD: microelectronics; production of light-emitting diodes.

SUBSTANCE: the invention is pertinent to microelectronics and may be used in production of light-emitting diodes. Electroluminescent polymeric nanocomposite material contains 50-99.5 mass % of polymer - water-soluble polyphenylamine with electron-hole conductance, and 50-0.5 mass % of an electroluminescing organic ingredient in the form of J- component units - a cyanine dye, a squaryl dye or a porphyrin. For production of the electroluminescent material first solve polyphenylamine in water, then introduce a powder of the indicated dye. Formation of J- component units fix according to a change of the solution color. Produced nanocomposite material is applied on the current-conducting substrate, dried. Then apply a layer of a metal-cathode. The invention allows to produce electroluminescent layers with a band of electroluminescence from 400 up to 1600 nm having high characteristics, for instance, luminance and efficiency.

EFFECT: the invention ensures production of electroluminescent layers with a band of electroluminescence from 400 up to 1600 nm having high luminance and efficiency.
