METHOD FOR PRODUCING MULTILAYER CUO/C NANOCOMPOSITE FILMS WITH SENSOR PROPERTIES IN WIDE SPECTRAL OPTICAL RANGE Russian patent published in 2023 - IPC C01B32/168 C01G3/02 C25D13/02 B82B3/00 B82Y30/00 B82Y40/00 

FIELD: nanotechnology; photovoltaics.

SUBSTANCE: used for the manufacture of highly sensitive optical sensors in a wide spectral range from ultraviolet to infrared radiation. At the first stage, ultrasonic dispersion of solutions of functionalized multi-walled carbon nanotubes is carried out at a power of 50 W for 30 minutes. At the second stage, the resulting colloidal system is centrifuged at a rotation speed of 1000 rpm until particles with a maximum size of up to 50 nm are formed. At the third stage, multilayer CuO/C nanocomposite films are formed layer-by-layer by electrophoretic synthesis, using glass substrates with prefabricated copper electrodes, between which colloidal solutions obtained after centrifugation are applied dropwise, applying further drops of a colloidal solution on top of the formed layers and carrying out electrophoretic synthesis.

EFFECT: CuO/C nanocomposite film obtained in this way can contain 10 layers and has sensory properties in the spectral range from 200 to 1100 nm; when irradiated with white light with an intensity of up to 8.5 mW/cm^2, an electromotive force (EMF) of up to 2.3 mV occur.
