Abstract Perovskite light‐emitting diodes (Pero‐LEDs) have garnered significant attention due to their exceptional emission characteristics, including narrow full width at half maximum, high color purity, and tunable colors. Recent efficiency operational stability advancements positioned Pero‐LEDs as a promising next‐generation display technology. Extensive research review articles on the compositional engineering defect passivation of perovskite layers substantially contributed development multi‐color high‐efficiency Pero‐LEDs. However, crucial aspect charge transport layer (CTL) modulation in remains relatively underexplored. CTL not only impacts carrier injection balance but also plays critical role passivating surface, blocking ion migration, enhancing crystallinity, improving light extraction efficiency. Therefore, optimizing CTLs is pivotal for further Pero‐LED performance. Herein, this discusses roles categorizes both reported potential materials. Then, various optimization strategies are presented, alongside an analysis selection criteria high‐performance Finally, summary outlook advance performances provided.

The unique optical properties of perovskite quantum dots (PQDs), particularly the tunable photoluminescence (PL) across visible spectrum, make them a promising tool for chlorinated detection. However, correlation between fluorescence emission shift behavior and interface phase transformation in PQDs has not been thoroughly explored. In this study, we synthesized CsPbBr3 via hot-injection method demonstrated their ability to detect volatile compounds such as HCl NaOCl through halide exchange process PQDs' solid thin film vapor phase. This process, which occurs alongside chloride (Cl) bromine (Br) ion atom rearrangement, leads sequential structural changes: initial cubic Pm3̅m transitions CsPb2BrxCl5–x tetragonal I4/mcm phase, subsequently transforms into CsPbBrxCl3–x orthorhombic Pnma detailed exploration proposed mechanism during detection with films, supported by X-ray diffraction (XRD) analysis PL spectrum over time, revealed high sensitivity vapor. limit (LOD) was determined be 0.02 ppm visual recognition 0.005 spectra. Additionally, LOD established at 0.50 ppm, facilitated photolysis reaction accelerating conversion under UV light irradiation. These insights have enriched our understanding mechanisms involved broadened potential use probes ions.
