Molecularly Designed, Nitrogen-Functionalized Graphene Quantum Dots for Optoelectronic Devices

Nitrogen‐functionalized graphene quantum dots (NGQDs) with tailorable optical properties are prepared by a versatile technique, which allows the highest occupied molecular orbital/lowest unoccupied molecular orbital energy levels and energy gaps to be continuously varied. The integration of NGQD lay...

Zusammenfassung:Nitrogen‐functionalized graphene quantum dots (NGQDs) with tailorable optical properties are prepared by a versatile technique, which allows the highest occupied molecular orbital/lowest unoccupied molecular orbital energy levels and energy gaps to be continuously varied. The integration of NGQD layers into the structures significantly improves the performance of optoelectronic devices.
