“…With the increasing demands for the performance of UV PDs in modern military and civil applications, meeting the “5 S” requirements is crucial: high sensitivity, high signal-to-noise ratio, spectral selectivity, fast response speed, and high stability [ 33 , 105 , 120 – 122 ]. UV PDs based on a single wide bandgap semiconductor material may not fulfill all these diverse purposes.…”

Ultraviolet (UV) light, invisible to the human eye, possesses both benefits and risks. To harness its potential, UV photodetectors (PDs) have been engineered. These devices can convert UV photons into detectable signals, such as electrical impulses or visible light, enabling their application in diverse fields like environmental monitoring, healthcare, and aerospace. Wide bandgap semiconductors, with their high-efficiency UV light absorption and stable opto-electronic properties, stand out as ideal materials for UV PDs. This review comprehensively summarizes recent advancements in both traditional and emerging wide bandgap-based UV PDs, highlighting their roles in UV imaging, communication, and alarming. Moreover, it examines methods employed to enhance UV PD performance, delving into the advantages, challenges, and future research prospects in this area. By doing so, this review aims to spark innovation and guide the future development and application of UV PDs.

“…Another deposition technique that could address the challenge of precisely controlling the deposition rate of the materials is pulsed-laser deposition (PLD). [165,168,169] PLD is similar to TE technique, that is, precursors are rapidly projected from the source to the substrate in vacuum, but the energy needed to evaporate them is provided by the UV laser irradiation rather than the traditional heat source. [165] Zhang et al reported a controllable and convenient PLD method to produce the CsCu 2 I 3 films.…”

Recently, the newly‐emerging lead‐free metal‐halide materials with less toxicity and superior optoelectronic properties have received wide attention as the safer and potentially more robust alternatives to lead‐based perovskite counterparts. Among them, ternary copper halides (TCHs) have become a vital group due to their unique features, including abundant structural diversity, ease of synthesis, unprecedented optoelectronic properties, high abundance, and low cost. Although the recent efforts in this field have made certain progresses, some scientific and technological issues still remain unresolved. Herein, a comprehensive and up‐to‐date overview of recent progress on the fundamental characteristics of TCH materials and their versatile applications is presented, which contains topics such as: i) crystal and electronic structure features and synthesis strategies; ii) mechanisms of self‐trapped excitons, luminescence regulation, and environmental stability; and iii) their burgeoning optoelectronic devices of phosphor‐converted white light‐emitting diodes (WLEDs), electroluminescent LEDs, anti‐counterfeiting, X‐ray scintillators, photodetectors, sensors, and memristors. Finally, the current challenges together with future perspectives on the development of TCH materials and applications are also critically described, which is considered to be critical for accelerating the commercialization of these rapidly evolving technologies.
