摘要

Perovskite light-emitting diodes (LEDs) are attractive because of their high efficiency and narrow emission. However, most of the current research on perovskite LEDs with primary color emission is focused on performance enhancement. Only a few studies focused on perovskite white LEDs. Here, we realized a perovskite white light-emitting diode with a single emissive layer by mixing the emission from a sky-blue perovskite material and an orange-near infrared (NIR) organic compound. Compounds with orange-NIR emission are synthesized and the influence of the compounds on the perovskite films is investigated by absorption and photoluminescence spectroscopy, X-ray diffraction, scanning electron microscopy and confocal laser-scanning fluorescence microscopy. Perovskite white LEDs were realized with CIE chromaticity coordinates of (0.3, 0.49), which are approaching the ideal pure white emission coordinates (0.33, 0.33).
