Abstract:Lead halide perovskite (LHP) nanocrystals (NCs) are witnessing
tremendous success in LED and display technology applications for
their defect tolerance properties and near-unity photoluminescence
quantum yield (PLQY). Despite this success, thermally assisted PL
quenching in LHP NCs is a major obstacle during the operation of devices
at a higher temperature. To overcome this obstacle, we have introduced
an effective washing-assisted short-chain capping ligand engineering
by 4-fluorobenzylammonium bromide (4FBAB… Show more
