Advanced Functional Materials, EarlyView.ABSTRACT Metal oxide (MOx)‐based NO2 gas sensors typically require high temperatures or ultraviolet light, limiting their practical use. To enable visible‐light activation at room temperature, efficient and stable photosensitizers should be integrated with nanostructured MOx hosts.

Chemical and Structural Diversity of Hybrid Layered Double Perovskite Halides [PDF]
Journal of the American Chemical Society, 2019 Hybrid halide double perovskites are a class of compounds attracting growing interest because of their richness of structure and property. Two-dimensional (2D) derivatives of hybrid double perovskites are formed by the incorporation of organic spacer cations into three-dimensional (3D) double perovskites.

Lead‐Free Halide Double Perovskites: Structure, Luminescence, and Applications [PDF]
Small Structures, 2020 Organic–inorganic halide perovskites have attracted extensive attention due to their excellent optoelectronic properties. However, the toxicity of heavy atom Pb2+ and instability overshadow further commercial applications, motivating researchers to explore alternative analogues to overcome these disadvantages. Lead‐free halide double perovskites (HDPs),

Trap‐Assisted Transport and Neuromorphic Plasticity in Lead‐Free 2D Perovskites PEA2SnI4
Advanced Functional Materials, EarlyView.An artificial retina built from lead‐free layered perovskite (PEA)2SnI4 converts light input into a persistent photocurrent and sums successive flashes over time. Micro/nanocrystals integrated on electrodes act as synapse‐like pixels that perform temporal integration directly in hardware. This in‐sensor preprocessing merges detection and computation on
