Carbon Dots

- Overview

Carbon Dots (CDs) or Carbon Quantum Dots (CQDs) are carbon nanoparticles which are less than 10 nm in size and have some form of surface passivation. Surface passivation refers to a common semiconductor device fabrication process critical to modern electronics. It is the process by which a semiconductor surface such as silicon is rendered inert, and does not change semiconductor properties when it interacts with air or other materials.

Carbon dots (CDs), known as a rising star of carbon-based nanomaterials, have attracted extensive attention in diverse fields such as biosensing, drug delivery, photodynamic therapy, photocatalysis, and biochemistry due to their unique structures and fascinating properties. In recent years solar cells.

Especially, due to their low toxicity, biocompatibility, excellent photostability, tunable fluorescence, excellent high-efficiency upconversion photoluminescence behavior, and photoinduced electron transfer ability, the excellent electronic and optical properties of CDs have been widely used in biomedicine and photocatalysis. application has attracted more and more attention.

- The Key Difference between Carbon Dots and Quantum Dots

Carbon dots and quantum dots come under the field of quantum mechanics. These are small nanoscale particles. The key difference between carbon dots and quantum dots is that carbon dots are small carbon nanoparticles, whereas quantum dots are small semiconductor particles.
