Abstract Optimizing the architecture of perovskite light‐emitting diodes (PeLEDs), such as incorporating inorganic hole transporting layers (HTLs), is crucial for enhancing their operational stability. Nickel oxide (NiO x ) offers a unique combination intrinsic stability, good electron‐blocking properties, excellent solution processability, and tunable optoelectronic making it an ideal HTL. Understanding basic properties NiO , customizing its energy level help address limitations in injection, enabling more efficient stable display devices. This review begins with overview band structure surface chemistry focusing on structure‐activity relationship between semiconductor properties. In following section, synthetic solution‐process addressed. The emphasis placed possible correlation morphology level. Next, strategies tuning are summarized. Finally, brief prospect ‐based PeLEDs provided. It hoped this provides new viewpoint PeLEDs.

Self-assembled monolayers (SAMs) have gained significant attention as an interfacial engineering strategy for perovskite solar cells (PSCs) due to their efficient charge transport ability and work function tunability. While solution-based methods such dip-coating spin-coating are widely used SAM deposition, challenges non-uniform coverage, solvent contamination, limited control over molecular orientation hinder scalability reproducibility. In contrast, vacuum deposition techniques, including thermal evaporation, overcome these limitations by enabling the formation of highly uniform materials with precise thickness arrangement. Importantly, chemical interactions between layers, coordination bonding Pb2+ ions, play important role in passivating surface defects, modulating energy levels, promoting crystallization. These not only enhance wettability but also improve overall quality stability films. This review highlights advantages vacuum-deposited SAMs, strong layers improving properties critical scalable applications.
