High photoluminescent carbon based dots with tunable emission color from orange to green

A one-pot hydrothermal method was proposed for the synthesis of carbon based dots (CDs) with high quantum yield and controllable long-wavelength photoluminescence (PL). The PL mechanisms of the CDs were discussed, and a common model has been proposed. Furthermore, the obtained CDs showed excellent b...

Zusammenfassung:A one-pot hydrothermal method was proposed for the synthesis of carbon based dots (CDs) with high quantum yield and controllable long-wavelength photoluminescence (PL). The PL mechanisms of the CDs were discussed, and a common model has been proposed. Furthermore, the obtained CDs showed excellent biocompatibility and high PLQYs (more than 20%), and presented great potential bio-applications.
