Abstract

The achievement of a full-width at half-maximum (FWHM) below 30 nm in pure-red PeQDs synthesized at room temperature, which is essential for ultra-high-definition television applications, has rarely been reported. Herein, we report the narrowest FWHM of 27 nm reported to date at room temperature, enabled by a stable A-site cation exchange employing lecithin.
