Abstract: An object is to provide a method of manufacturing luminescent nanocarbon with which the luminescent nanocarbon can be efficiently manufactured in large amounts. This method is to manufacture luminescent nanocarbon (Product) from a raw material aqueous solution that contains a carbon source compound and a nitrogen source compound. This method includes a reaction step of heating the raw material aqueous solution from a storage container (Reservoir) in a heating section (Furnace) to react the raw material aqueous solution at a reaction temperature of 100° C. or higher and 500° C. or lower and a cooling step of cooling a reaction solution that contains a reaction product generated in the reaction step. The cooling step is carried out in a bath (Ice bath).
