DEVICE FOR PRODUCING PHOTONIC-CRYSTALLINE FILMS ON SUBSTRATE BY VERTICAL DRAWING FROM COLLOIDAL SOLUTION Russian patent published in 2024 - IPC C23C26/00 

FIELD: performing operations.

SUBSTANCE: invention relates to devices for producing photonic-crystalline films on a substrate by vertical drawing from a colloidal solution and can be used in the technological process of producing a thin colloidal film of different topography (solid, insular, with a periodic structure, amorphous) and thickness (monolayer, multilayer structures). Device for producing photonic-crystalline films on a substrate by vertical drawing from a colloidal solution comprises a metal base, a middle part of the housing with the possibility of isolating the working area from external effects, an upper part of the housing with a control system and a stepper motor and a substrate holder. Top of the metal base has a recess with the possibility of arranging the heating and cooling elements of the table, on which there is a colloidal solution and a recess for wires. Metal base comprises working table for installation of container with colloidal solution. Device design additionally contains a microclimate control and correction system in the form of two Peltier elements and a liquid heat exchange circuit, the middle part of the housing, made of plastic, contains a fan, temperature and humidity sensors. Inextensible tape is used for connection of substrate holder with drawing mechanism.

EFFECT: reproducible production of single- or multilayer photonic-crystalline films with given topography by vertical drawing from colloidal solutions.
