Abstract Reduced‐dimensional perovskites (RDPs), a large category of metal halide
perovskites, have attracted considerable attention and shown high potential in the fields of …

Perovskite light‐emitting diodes (PeLEDs) that can be air‐processed promises the
development of displaying optoelectronic device, while is challenged by technical difficulty …

Despite the substantial progress in sky‐blue (480− 495 nm) perovskite light‐emitting diodes
(PeLEDs), the pure‐blue PeLEDs (< 480 nm) merely show moderate performances. As a …

Nickel oxide (NiO x) has been extensively adopted as a promising hole transport material for
perovskite light-emitting diodes (PeLEDs). However, its shallow valence band induces a …

The device performance of deep‐blue perovskite light‐emitting diodes (PeLEDs) is primarily
constrained by low external quantum efficiency (EQE) especially poor operational stability …

The halide postdeposition treatment technique is a widely used strategy for mitigating
defects in perovskite. However, when applied to mixed‐halide perovskites, it often leads to …

Blue light-emitting diodes (LEDs) play a crucial role in full-color displays, with blue
perovskite materials emerging as promising candidates for blue LEDs. However, the …

Fluorinated additives are proposed to address the issue of domain polydispersity in quasi‐
2D perovskites. However, the lack of established screening criteria for these additives …

Blue perovskite light-emitting diodes (PeLEDs) still remain poorly developed due to the big
challenge of achieving high-quality mixed-halide perovskites with wide optical bandgaps …
