Carbon Quantum Dots and Recent Developments in Energy Applications: A Review

The type of nanomaterial that successfully attracts researchers towards itself is called Carbon Quantum Dots (CQDs) having exceptional properties and being full of advantages such as being effective in cost, friendly to the environment, low toxicity, and many more. The following review explains the properties of CQDs and also some recent state-of-the-art developments of CQDs in the field of Energy. Initially, the first section is entirely focused on the optical properties of CQDs such as Photoluminescence (PL), Chemical Luminescence (CL), Electrochemiluminescence (ECL), Room Temperature Phosphorescence (RTP), and Absorption property of CQDs. Furthermore, the next section is about the energy applications of CQDs are mainly focused which include Photovoltaics, Hydrogen Evolution Reaction (HER), Lithium-Ion Batteries (LIBs), and Supercapacitors. In addition, we also discussed the challenges and future prospects for CQDs
