Abstract

Graphitic carbon nitride (g-C₃N₄) quantum dots (CNQDs) were prepared from bulk g-C₃N₄ directly by a thermal-chemical etching process. The CNQDs show strong blue emission as well as upconversion behavior, which can be used as universal energy-transfer components in visible-light-driven metal-free photocatalytic systems.
