Quantum Dots

Quantum dots (QDs) materials have received great attention because of their unique electronic, optical and chemical properties. We introduced synthesis of QDs such as graphene quantum dots (GQDs), Carbon Dots (CDs), PbS, FeS, and Perovskite QDs. The developed GQDs containing N atoms were synthesised using a facile, inexpensive, and environmentally friendly hydrothermal reaction of urea and citric acid. We also investigated in detail the effect of the GQDs’ C–N configurations on their photoluminescence (PL) properties. The dots were confirmed as spherical, with an average diameter of 2.17 nm and the C–N configurations of the GQDs substantially affected their PL intensity. We also studied a PL mechanism for the hydrothermally synthesized GQDs.
