Highly Efficient Perovskite‐Quantum‐Dot Light‐Emitting Diodes by Surface Engineering. Issue 39 (16th August 2016) - Pan, Jun
Abstract : A two‐step ligand‐exchange strategy is developed, in which the long‐carbon‐ chain ligands on all‐inorganic perovskite (CsPbX3, X = Br, Cl) quantum dots (QDs) are replaced with halide‐ion‐pair ligands. Green and blue light‐emitting diodes made from the halide‐ion‐pair‐capped quantum dots exhibit high external quantum efficiencies compared with the untreated QDs.
