Recent Advancements and Perspectives of Low-Dimensional Halide Perovskites for Visual Perception and Optoelectronic Applications

Abstract

This review uniquely bridges the relationship between 0D, 1D, and 2D structural motifs of halide perovskites and their distinct optoelectronic properties; such as photoluminescence, charge transport, and excitonic behavior and how these impact performance across various devices (e.g., LEDs, photodetectors, synapses). This dimensional-property-functionality mapping is not extensively covered in previous reviews. Unlike many earlier reviews focused solely on photovoltaics or LEDs, this article expands into emerging fields like artificial synapses and visual perception-related electronics, offering insights into how low-dimensional perovskites could enable next-generation neuromorphic and intelligent sensing systems. The review doesn't just summarize the field it also critically evaluates current limitations in scalability, environmental stability, and device integration, and provides future directions to overcome these, particularly through material design and interfacial engineering, making it highly relevant for guiding industrial research.
