One-step synthesis of graphene quantum dots |
| abstract |
Methods of making graphene quantums dots are provided. The methods can produce graphene quantum dots with a monodisperse size distribution. The graphene quantum dots are produced, via one-pot synthesis, from a graphene source and a strong oxidizing mixture at an elevated temperature. The strong oxidizing mixture can contain one or more permanganates and one or more oxidizing acids. Exemplary permanganates include sodium permanganate, potassium permanganate, and calcium permanganate. Exemplary oxidizing acids include nitric acid and sulfuric acid. The graphene quantum dots can have an average particle size of between about 1 nm and 20 nm and a monodisperse size distribution. For example, the size distribution can have a span about 1 or less and/or a coefficient of variance of about 0.5 or less. About 40% or more of the graphene quantum dots can have a diameter within ±5 nm of the average particle size of the graphene quantum dots. |
