“…Metallic Ag and its alloys with paragroup elements (such as AgCu, AgCo), featuring modified d‐band centers, have demonstrated attractive ORR activity in alkaline electrolytes, facilitating the complete reduction of O 2 through a 4e − pathway to OH − with good stability. [ 117,118 ] Additionally, Ag exhibits reversible cathodic activity, making it a promising choice for Zn‐Ag batteries with high power output. For example, Peng et al developed a self‐supporting cathode using a nanoporous Ag 2 Al intermetallic compound for the cathode material.…”

Rechargeable Zn‐air batteries (ZABs) are regarded as an attractive green energy storage technology, featured with large theoretical energy densities and intrinsic high safety factors. However, hindered by the sluggish kinetics of both oxygen reduction reaction and oxygen evolution reaction, rechargeable ZABs are confronted with some critical challenges such as low operating voltage, poor energy efficiency, and limited cycle life. Zn‐air‐based hybrid batteries (ZAHBs), integrating the advantages of a conventional ZAB with supplementary redox reactions, have emerged as a promising solution to address those challenges. Based on working principles, the hybrid batteries can be categorized into two groups: Zn‐M/air hybrid batteries (M = Ni, Co, Ag, Cu, and Mn) and Zn‐X/air hybrid batteries (X = KI, ethanol, and urea), which can achieve improved energy efficiency and density by optimizing charge–discharge voltage. Herein, a comprehensive overview of ZAHBs is provided, including the classification, latest progress, and electrochemical properties, as well as detailed discussion of relevant mechanisms. Moreover, the perspectives and opportunities for future research in the field of hybrid battery systems are also outlined. This review shall give helpful guidance on the design and application of ZAHBs, and provide important insights into the development of new electrochemical energy storage systems.

“…Wavelength‐selective photodetectors (PDs) are responsive to lights of particular wavelengths or in a specific band window, which has extensive applications in image sensing, optical communication, and environment monitoring. [ 1–5 ] Among them, visible PDs and X‐ray PDs have attracted more attention due to today's ever‐increasing demand for imaging technologies in the fields of machine vision and X‐ray tomography. [ 6–9 ] Generally, the wavelength recognition in commercial visible image sensors is enabled by the integration of silicon (Si)‐based PDs and Bayer filters, in which the Bayer filters with a 2 × 2 red‐green‐blue‐green pattern (RGBG) for each pixel are placed on the top of the PD arrays, complicating the device fabrication and challenging the high‐density integration.…”

Spectral sensing plays a crucial part in imaging technologies, optical communication, and other fields. However, complicated optical elements, such as prisms, interferometric filters, and diffraction grating, are required for commercial multispectral detectors, which hampers their advance toward miniaturization and integration. In recent years, metal halide perovskites have been emerging for optical-component-free wavelength-selective photodetectors (PDs) because of their continuously tunable bandgap, fascinating optoelectronic properties, and simple preparation processes. In this review, recent advances in wavelength-selective perovskite PDs, including narrowband PDs, dual-band PDs, multispectral-recognizable PDs, and X-ray PDs, are highlighted, with an emphasis on device structure designs, working mechanisms, and optoelectronic performances. Meanwhile, the applications of wavelength-selective PDs in image sensing for single-/dual-color imaging, full-color imaging, and X-ray imaging are introduced. Finally, the remaining challenges and perspectives in this emerging field are presented.

Despite the ultra‐high photoluminescence quantum yield (PLQY) of 0D hybrid manganese halides as state‐of‐the‐art luminescent materials, intrinsic water stability remains an unsurpassable barrier due to the serious hygroscopicity of the hydrogen‐bonding structure. Herein, a synthetic strategy that realizes adjustable emission color and high water resistance in a 0D hybrid manganese chloride family based on the same cation of [H2TMDAP]2+ (TMDAP = N,N,N′,N′‐tetramethyl‐1,3‐diaminopropane) is reported. Specifically, direct solution or solid‐state reaction of precursor materials generates [H2TMDAP]3[MnCl4]2[Mn2Cl6], while additional Zn2+‐doping as a structural directing agent results in [H2TMDAP]Mn0.63Zn0.37Cl4. Functionally, the [Mn/ZnCl4]2− tetrahedron based [H2TMDAP]Mn0.63Zn0.37Cl4 displays green light emission at 521 nm with a PLQY of 63.9%. [H2TMDAP]3[MnCl4]2[Mn2Cl6] is composed of a [MnCl6]4− octahedron based [Mn2Cl6]2− chain and a discrete [MnCl4]2− tetrahedron, but it only exhibits single red emission at 628 nm with a PLQY of 48.1%. Compared with water‐instable [H2TMDAP]Mn0.63Zn0.37Cl4, [H2TMDAP]3[MnCl4]2[Mn2Cl6] represents extraordinary chemical stability in humid air and water over 1 month, manifested by an unchanged structural lattice and sufficient emission intensity. Significantly, the ultra‐high water proof performance of [H2TMDAP]3[MnCl4]2[Mn2Cl6] is nearly unmatchable among all previously reported manganese halides as far as is known. The combined merits of tunable emission wavelength, high PLQY, and stability highlight the potential applications of title materials in solid‐state lighting and display diodes.
