Graphene quantum dots (GQDs) are nanoscale fragments of graphene that demonstrate strong quantum confinement and edge effects, resulting in a bandgap that is lacking in graphene. A bandgap in addition to tunable size, shape, and functionality gives GQDs a variety of unique and interesting properties, such as strong photoluminescence and outstanding electrical, thermal, and mechanical properties. Chlorine functionalized graphene quantum dots (Cl-GQDS), also called chlorine-doped GQDs, are capturing the interest of researchers specifically for antibacterial and photovoltaic applications.
Antibacterial – Cl-GQDs demonstrate enhanced singlet oxygen generating abilities, robust scavenging performance, and efficient rates of free radical production, all of which lend themselves well to pro- and antibacterial activities.
Photovoltaics – Raman studies show that G and 2D peaks of GQDs are softened by chlorine doping, resulting in n-type doping. In Cl-GQD based photovoltaic detectors, both light absorbing and electron-accepting roles for photodetection have been observed; the result is an exceptionally high ratio of photocurrent to dark current.
High-quality chlorine functionalized graphene quantum dots are available in concentrations up to 2mg/ml in water. These solutions are transparent under natural light and emit a blue light when exposed to UV light. Contact us today for more information about this or any of our other advanced nanomaterials.
