To enhance the efficiency of vacuum-deposited inorganic CsPbBr3 perovskite light-emitting devices by passivating nonradiative defects and balancing charge transport.
Fabricated inorganic perovskite light-emitting devices using vacuum thermal deposition to form a CsPbBr3 emission layer.
Introduced an ultrathin 2-phenylethanamine bromide interlayer to supply PEA+ cations for surface defect termination and charge regulation.
Achieved a low device turn-on voltage of 3 V.
Reached a maximum current efficiency of 14.64 cd A–1 and an external quantum efficiency of 4.10% following interlayer modification.
