The Global Market for Graphene Quantum Dots

0

Carbon quantum dots (CDs, CQDs or C-dots) and graphene quantum dots (GQDs) have recently emerged as a new class of QD materials. GQDs possess unique optical and electrical properties such as:

  • strong photoluminescence
  • biocompatibility
  • exhibit band gap (unlike graphene sheets).

As a result they are being widely investigated for applications in optoelectronics, biomedicine and sensors. GQDs are composed of single or very few graphene lattices (<10) that have quantum confinement effect and edge effects. Unlike graphene sheets, they exhibit band gap that is responsible for their unique electrical and optoelectronic properties.

GQDs are promising materials as substitutes for Cd, Ir, Ga, S, Se and P quantum dots (QDs) and possess unique structural and photophysical properties. Compared with Quantum Dots (QDs), GQDs are potentially superior due to their high photostability against photobleaching and blinking, biocompatibility, and low toxicity.

Report contents include:

  • Properties of graphene quantum dots (GQDs).
  • Applications of graphene quantum dots (GQDs).
  • Addressable markets for graphene quantum dots (GQDs).
  • Graphene quantum dots (GQDs) roadmap.
  • Production and pricing.
  • Company profiles.
