Abstract
Metal halide perovskite, regarded as a potential material for
next-generation display and lighting applications, has attracted
great attention [1,2]. The development of blue perovskite lightemitting
diodes (PeLEDs) remains stagnant compared with their
green and red counterparts in recent years [3–8]. Meanwhile,
among the emitters of different blue emission regions, the development
of deep-blue PeLEDs urgently required by the display
application lagged significantly behind. Therefore, conducting
research on deep-blue PeLEDs (<460 nm) to achieve the desired
color gamut in the range of the Commission Internationale de
I’Eclairage (CIE) color coordinates approaching (0.131, 0.046) that
fulfill the Rec. 2020 specification holds paramount importance.
However, obtaining deep-blue emission in perovskites through
the straightforward implementation of the common strategies
involving excessive chloride incorporation and dimensional reduction
presents a significant challenge.
