Abstract

A perovskite LED with a perovskite film treated under optimum thermal annealing conditions exhibits a significantly enhanced long-term stability with full coverage of the green electroluminescence emission due to the highly uniform morphology of the perovskite film.

Keywords: electroluminescence; long-term stability; perovskite light-emitting diodes; perovskites.
