摘      要：With superior photoluminescence quantum yields(PLQYs),tunable bandgap,high color purity and solution pro-cessibility[1,2],metal halide perovskite nanocrystals(PNCs)with a general formula of ABX_(3)(A=CH_(3)NH_(3)+(MA+),CH(NH_(2))_(2)^(+)(FA^(+))and Cs^(+),B=Pb^(2+),Sn^(2+)and Mn^(2+),X=Cl-,Br-and I-)emerge as promising luminescent materials in light-emitting diodes(LEDs)and solid-state lighting[2−4].Since elec-troluminescence(EL)of PNCs was first observed in CsPbBr3 PNC-based LEDs with an external quantum efficiency(EQE)of 0.07%in 2015[5],the efficiencies for different LEDs have been significantly boosted.
