Title:
METHOD FOR PRODUCING LUMINESCENT NANOCARBONS
Document Type and Number:
WIPO Patent Application WO/2021/054462
Kind Code:
A1
Abstract:
In order to provide a method by which luminescent nanocarbons that exhibit strong luminescence within a long wavelength region of from 500 nm to 620 nm when excited by light that has a wavelength shorter than the emission wavelength are able to be produced, a method for producing luminescent nanocarbons according to the present invention is provided with a reaction step wherein a starting material solution is reacted to form luminescent nanocarbons. With respect to this method for producing luminescent nanocarbons, the starting material solution contains: at least one compound that is selected from the group consisting of benzene compounds having a hydroxy group, aliphatic hydroxy acids and aliphatic dicarboxylic acids; and at least one compound selected from among o-phenylenediamine and 1, 5-naphthalenediamine.
