Understanding the charge transfer mechanism in CsPbBr 3 nanocrystals and nitrogen-doped carbon quantum dot heterostructures: effect of nanocrystal encapsulation

The charge transfer among the CsPbBr 3 nanocrystals (NCs) and nitrogen-doped carbon quantum dots (NCQDs) is feasible due to the bonding of the N-state of NCQDs and Pb-atoms present in the CsPbBr 3 structure.
