Abstract

Quasi-2D perovskites with the BA:MA molar ratio equal to 3:3 show a remarkable PLQY exceeding 80%, thanks to the use of an electron donor as the passivating agent. These films have been applied in LEDs that exhibit high brightness exceeding 1000 cd m^-2 and current efficiencies >3 cd A^-1.
