Such a mechanism may be of great importance for light harvesting, photocatalysis and optoelectronics.4enPublisher Copyright: © The Royal Society of Chemistry 2016.Quantum-confined bandgap narrowing of TiO<sub>2</sub> nanoparticles by graphene quantum dots for visible-light-driven applications201610.1039/c6cc03302d84978712019
