Abstract

Perovskite thin-film electroluminescence devices are prepared, opening up a new optical application of perovskite materials. With increasing driving voltage, the intensity of electroluminescence increases dramatically. High-quality red color is produced and the working voltage for whole-surface electroluminescence is as low as 10 V.
