Prolonging the Lifetime of Quasi-2D Perovskite Blue LEDs via DMAcPA Doping for Defect Passivation

In this study, we developed highly efficient quasi-2D blue perovskite light-emitting diodes (PeLEDs) by incorporating (4-(2,7-dibromo-9,9-dimethylacridin-10(9H)-yl)butyl)phosphonic acid (DMAcPA) into the perovskite precursor solution. DMAcPA significantly improved the crystal quality by...
