Metal halide perovskites, a cost-effective class of semiconductos, hold great promise for display technologies that demand high-efficiency, color-pure light-emitting diodes (LEDs). Early research on three-dimensional (3D) perovskites showed low radiative efficiencies due to modest exciton binding energies. To inprove luminescence, reducing dimensionality or grain size has been common approach. However, dividing the perovskite lattice into smaller units may hinder carrier transport,...
Abstract The combination of organic spacer cations and mixed‐halides to produce multiphase quasi‐2D perovskites is a promising strategy for fabricating blue perovskite light‐emitting diodes (PeLEDs). However, insufficient energy transfer, trap‐assisted recombination exciton‐phonon coupling lead significant non‐radiative losses. Here, co‐spacer engineering binding guanidinium (GA + ) ortho ‐fluorophenylethylamium (oF‐PEA through hydrogen bonds proposed prepare mixed‐halide films with high...
Abstract:During the past few years,the performance of perovskite light-emitting diodes(PeLEDs) has been greatly improved.Constructing quasi-2D perovskites with quantum wells is an effective approach to develop high PeLEDs.And organic cations large size are crucial perovskites,which play important role in regulating film structures and optoelectronic properties perovskites.Here we incorporated 2-fluorophenethylammonium bromide (ortho-substituted o-FPEABr) 4-fluorophenethylammonium...
