Red Perovskite Emitters for Colour Conversion and LEDs

Perovskites are promising light-emitting materials for colour conversion and direct electroluminescence with the potential to enable advanced display architectures. While early commercial development has focused on green, red emitters are needed for both in-pixel and backlight film colour conversion. Here we report on the recent developments on red emitters tailored for wide-colour gamut and power efficiency. The materials show very high colour stability and are suitable for use in films, pixels, and LEDs.
