“…The traditional chemical method for metal ion doping mentioned above has difficulty achieving uniform doping, especially in high concentration metal ion doping of single crystals. ,− As a physical doping method, ion implantation can control the doping elements in the form of pure ions. In addition, it also accurately controls the ion concentration, depth, and distribution of doped ions in the implanted target such as single crystal, and the results have good repeatability. , Our group successfully modified the properties of several halide perovskite single crystals and other semiconductors by metal ion implantation, which show that metal ion implantation can improve the light absorption of halide perovskite materials, thus enhancing the device performance. ,, …”

All-inorganic halide perovskite single crystals have attracted significant attention in optoelectronic fields on account of their outstanding optoelectronic properties. Photodetectors (PDs) based on CsPbBr 3 single crystal exhibit high responsivity (R) and external quantum efficiency (EQE) due to the direct optical band gap, large optical absorption throughout the visible spectrum range, and long-term stability. Herein, we prepared the centimetersize CsPbBr 3 perovskite single crystal and utilized Zr ion implantation to modify the photoelectric properties of single crystals. The optical band gap of the CsPbBr 3 single crystal decreases from 2.24 to 2.12 eV, and the absorption intensity increases after Zr ion implantation. The R and EQE of the CsPbBr 3 single crystal photodetector modified by Zr ion implantation are 1.0 A W −1 and 294%, respectively, with a light intensity of 3.8 mW cm −2 and a 5 V bias under 425 nm illumination, which are ten times larger than that of the pristine devices. Meanwhile, the first-principles calculation results show that the introduction of Zr ions decreases the band gap and that the Zr 4d orbit contributes to the conduction band minimum (CBM), which facilitates carrier transport in Zr ion implanted CsPbBr 3 single crystals. The results show that Zr ion implantation is an effective strategy to improve the performance of the CsPbBr 3 single-crystal-based PDs.

The development of green, renewable energy conversion and storage systems is an urgent task to address the energy crisis and environmental issues in the future. To achieve high performance, stable, and safe operation of energy conversion and storage systems, energy materials need to be modified and fabricated through rationalization. Among various modification and fabrication strategies, ion beam technology has been widely used to introduce various defects/ dopants into energy materials and fabricate various nanostructures, where the structure, composition, and property of prefabricated materials can be further accurately tailored to achieve better performance. In this paper, we review the recent progress in the application of ion beam technology in material modification and fabrication, focusing on nanostructured energy materials for energy conversion and storage including photo-(electro-) water splitting, batteries (solar cells, fuel cells, and metal-ion batteries), supercapacitors, thermoelectrics, and hydrogen storage. This review first provides a brief basic overview of ion beam technology and describes the classification and technological advantages of ion beam technology in the modification and fabrication of materials. Then, modification of energy materials by ion beams is reviewed mainly concerning doping and defect introduction. Fabrication of energy materials is also discussed mainly in terms of heterojunctions, nanoparticles, nanocavities, and other nanostructures. In particular, we emphasize the advantages of ion beam technology in improving the performance of energy materials. Finally, we point out our understanding of challenges and future perspectives in applying ion beam technology for the modification and fabrication of energy materials.

Hydroelectrochemical energy storage has the characteristics of high energy density, fast response time, low maintenance cost, flexible and convenient installation, etc., and is a hot development direction of future energy storage technology. Aqueous zinc-ion batteries (AZIBs) with neutral or near-neutral electrolytes have attracted much attention due to their advantages of safety, reliability, abundant resources, and environmental friendliness. Mn-based oxides are widely used as cathode materials for AZIBs due to their high theoretical specific capacity and low toxicity. However, Mn-based oxides face structural collapse during charge–discharge cycles, resulting in rapid capacity decay. This paper reviews the electrochemical characteristics of different Mn-based oxides as cathodes, the energy storage mechanism involved in the charging and discharging process of Mn-based AZIBs, and the advantages of Mn resources. At the same time, combined with the latest research progress, the existing problems and feasible improvement methods are pointed out, and the future development trend is prospected.
