Abstract

Abstract : A controllable and reversible phase transformation between CsCu2 I3 and Cs3 Cu2 I5 is employed to fabricate electroluminescent WLEDs for the first time. Abstract : The stable and highly efficient yellow-emitting CsCu2 I3 is obtained in a nearly 100% yield based on a controllable and reversible phase transformation between all-inorganic perovskites. This effective strategy is successfully employed to fabricate high-quality electroluminescent white light emitting diodes (WLEDs) for the first time.
