“…Very recently, lanthanide-doped fluoride materials prepared by wet chemical methods were developed for high-resolution, flexible X-ray luminescence extension imaging. These materials prolonged radioluminescence and X-ray memory after the stoppage of the X-ray source, making it possible to fabricate flexible X-ray detectors [ 114 ]. After rational surface coating, the persistent luminescence intensity was enhanced by 6.5-fold, suggesting that the surface passivation can efficiently block the pathway of energy quenching by defects on the surface.…”

X-ray imaging is a low-cost, powerful technology that has been extensively used in medical diagnosis and industrial nondestructive inspection. The ability of X-rays to penetrate through the body presents great advances for noninvasive imaging of its internal structure. In particular, the technological importance of X-ray imaging has led to the rapid development of high-performance X-ray detectors and the associated imaging applications. Here, we present an overview of the recent development of X-ray imaging-related technologies since the discovery of X-rays in the 1890s and discuss the fundamental mechanism of diverse X-ray imaging instruments, as well as their advantages and disadvantages on X-ray imaging performance. We also highlight various applications of advanced X-ray imaging in a diversity of fields. We further discuss future research directions and challenges in developing advanced next-generation materials that are crucial to the fabrication of flexible, low-dose, high-resolution X-ray imaging detectors.

“…Interestingly, we found that the sample exhibits bright luminescence under X-ray irradiation through the transparent protective window in the process of X-ray powder diffraction, and thus we systematically tested the fluorescence emission of the sample under X-ray excitation [58,59]. The X-ray-induced emission performance of Sb 3+ -doped CaZnOS is shown in Fig.…”

Mechanoluminescent (ML) smart materials are expected to be used in stress sensors, new displays, and advanced flexible optoelectronic devices, because of their unique mechanical-to-light energy conversion properties. However, the narrow-range ML emission characteristics of single materials limit their application scope. In this work, we report on the broadband multimodal emission in Sb-doped CaZnOS layered semiconductors. A series of CaZnOS layer-structured powders with different Sb 3+ doping concentrations were synthesised using a high-temperature solid-phase method. The CaZnOS:Sb 3+ phosphor achieved a wide range of ML spectra (400-900 nm), adjustable photoluminescence with double luminescent peaks located at 465 and 620 nm, and the X-rayinduced luminescence characteristics were systematically studied. We have also achieved ultra-broad warm white light ML emission of Sb 3+ and Bi 3+ co-doped samples. Therefore, it can be expected that these ML phosphors will be used in smart lighting, displays, visible stress sensors, and X-ray imaging and detections.

“…Recently, Yu He, Qiushui Chen, Huanghao Yang, and co‐workers innovatively fabricated an upconversion nanoparticles–perovskite nanotransducer for broadband photodetection spanning from X‐rays to NIR. [ 203 ] The novel nanotransducer has the core–shell structure of lanthanide‐doped upconversion nanoparticles@mesoporous silica@MAPbX 3 (X = Cl, Br, or I), in which upconversion nanoparticles are the core and mesoporous silica is the shell incorporated with MAPbX 3 nanodots. After being exposed to NIR, core upconversion nanoparticles absorb NIR photons, then produce UV and blue emission to activate MAPbBr 3 nanodots by the re‐absorption process (Figure 15e).…”

Hybrid halide perovskites have been demonstrated to be prospective materials in optoelectronic devices due to their outstanding photoelectric properties and facile manufacturability by low‐cost and fast solution‐processed methods. Particularly, to meet increasingly potential applications in near‐infrared (NIR) detection and imaging, perovskites have been introduced and explored their roles, some of which achieve the comparable performance with traditional silicon counterparts. Here, the recent advancements of hybrid halide perovskite‐based NIR photodetectors and imaging arrays in terms of perovskite formation, device structures, working mechanisms, and device performances are reviewed. Pb perovskite‐based devices either employ sub‐bandgap absorption and intraband transition, or incorporate with narrow‐bandgap semiconductors to achieve NIR detection, which could reach the spectral response onset at 2.6 µm wavelength. Sn perovskite‐based devices employ the strategies of template‐assisted engineering and reducing additives to inhibit the oxidation of Sn2+ states for efficient detection. SnPb mixed perovskite devices employ compositional engineering, passivation strategies, crystallization tuning, and encapsulation to achieve efficient and long shelf‐life photodetectors with an external quantum efficiency of 70% at 940 nm wavelength. Finally, potential prospects are proposed, including spectral response extension, pixel integration, flexible devices, and stability, to advance perovskite‐based NIR detection and imaging toward commercial applications.
