Title:
METHOD FOR PRODUCING CUPROUS OXIDE, AND CUPROUS OXIDE FILM
Document Type and Number:
WIPO Patent Application WO/2024/090555
Kind Code:
A1
Abstract:
The present invention produces cuprous oxide having adequate performance. This method for producing cuprous oxide comprises a step in which a copper ink that is a liquid composition containing copper particles is obtained, a step in which the copper ink is applied or printed on a substrate to form a film, and a step in which the film of the copper ink formed on the substrate is dried and then heated in an atmosphere having an oxygen concentration of 10-21% by irradiation with light having wavelengths in a range of from visible to infrared regions to thereby oxidize and sinter the copper particles contained in the copper ink, thereby producing a sintered object made of cuprous oxide.
