Tóm tắt

Mixed-halide perovskite plays important role in wide-color gamut displays as a vital material for three primary colors. However, halide segregation and caused unstable spectra are the intrinsic problem in mixed-halide perovskite light-emitting diodes (PeLEDs) originating from the lattice strain and the resulting defects in perovskite quantum dots (PQDs). Here, smaller transition metal cations are applied to replace Pb
