Production method and carbon quantum dots of carbon quantum dots

摘要

PROBLEM TO BE SOLVED: To provide a method of producing a carbon quantum dot which enables producing a quantum dot simply and efficiently and a carbon quantum dot.SOLUTION: A method of producing a carbon quantum dot comprises: a carbon quantum dot formation liquid preparation step of mixing a carbon material with hydrogen peroxide to cause a decomposition reaction of carbon in the carbon material by hydrogen peroxide so as to prepare a carbon quantum dot formation liquid in which a carbon quantum dot derived from the carbon material is formed; and a carbon quantum dot acquisition step of separating hydrogen peroxide from the carbon quantum dot in the carbon quantum dot formation liquid to stop the decomposition reaction so as to acquire the carbon quantum dot.
