description | To provide a method for producing carbon quantum dots having high emission quantum yield through simple processes. A method for producing carbon quantum dots that solves the difficulty described above includes: preparing a mixture by mixing a crystalline compound containing boron, sulfur, or phosphorus, being solid at 1 atm and 25°C, and having crystallinity, and an organic compound having a reactive group; and preparing carbon quantum dots by heating the mixture at 100°C or higher and 300°C or lower substantially in the absence of a solvent. An amount of the crystalline compound in the mixture is 45 parts by mass or greater and 1000 parts by mass or less with respect to 100 parts by mass of the organic compound. |
