Abstract
Provided is a production method for a carbon-based light-emitting material that generates light having a wavelength of 500 to 700 nm when exposed to excitation light having a wavelength of 300 to 600 nm. The production method comprises a step for mixing and heating a starting material containing ascorbic acid, an acid catalyst containing an inorganic acid, and a solvent.
Claims7
A method for producing a carbonaceous luminescent material that, when exposed to excitation light having a wavelength of 300 to 600 nm, emits light having a wavelength of 550 to 700 nm, which method comprises the step of mixing together and heating an ascorbic acid-containing starting material, an inorganic acid-containing acid catalyst and a solvent.
