    Chelation strategy induced blue-shift for efficient deep-blue perovskite light-emitting diodes
    (2024-01-01) YAVUZ, İLHAN; Xia Y., Zhang Z., Zhou Y., Li Y., Wang B., Wang K., Chen C., Chen J., YAVUZ İ., Xing G., et al.
    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.
