Blue Luminescent Graphene Quantum Dots
Blue Luminescent Graphene Quantum Dots‚ Solution‚ CAS NO.: 7440-40-0
CAS NO.: 7440-40-0
Graphene quantum dots (GQDs) are nanoscale fragments of graphene that, unlike graphene, demonstrate robust quantum confinement and edge effects. This, combined with the ability to control their size, shape, and functionality, gives GQDs a number of unique properties, such as strong photoluminescence. Their relation to graphene gives GQDs superior electrical, thermal, and mechanical properties. And, unlike metal or silicon quantum dots, GQDs are photo stable and biocompatible. All this makes GQDs ideal for a number of state-of-the-art applications, including:
- Optical brightening
- Security tagging
- Drug delivery
- Markers for bioimaging
- Cellular imaging
- Fluorescent polymers
- Antibacterial systems
- Flash memory devices
High-quality blue luminescent graphene quantum dots from ACS Material are available in concentrations up to 20mg/ml in various solvents, including DMF, ethanol, IPA, NMP, or water. These solutions emit blue light (460nm) when excited with a 365nm UV beam. Contact us today for more information about this or any of our other advanced nanomaterials. Trust ACS Material for all your advanced research material needs.
