Perovskite nanocrystals for light-emitting diodes
文献摘要：
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 ABX3(A=CH3NH3+(MA+),CH(NH2)2+(FA+)and Cs+,B=Pb2+,Sn2+and Mn2+,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.The red and green LEDs demonstrated an EQE of＞23％and the highest EQE for blue LEDs reached 13.8％[6-8],comparable to conventional LEDs based on organ-ic emitters or metal chalcogenide(Ⅱ-Ⅵ)quantum dots(QDs)[9,10].
