Graphene quantum dots (GQDs) are nanoscale fragments of single- or multilayer graphene. GQDs demonstrate a number of exciting properties that make them attractive for energy, biological, optical, and environmental applications. These properties include low toxicity, chemical stability, photoluminescent stability, high transparency, a high surface area, and pronounced quantum confinement effects. The presence of quantum confinement effects means that GQDs, unlike graphene, contain a bandgap, which increases their versatility. GQDs also have four quantum states at any given energy level; semiconductor quantum dots only have two. The additional quantum states open up the possibility for use of GQDs in quantum computing.
Aminated graphene quantum dots are produced via the hydrothermal method. . All our advanced nanomaterials, including aminated GQDs, are produced to meet the highest standards of quality and consistency. Call today to speak to one of our experts for exact product details and specifications.
