“…As early as 2006, Wojtowicz et al reviewed spectroscopic and scintillator characterization of oxide perovskites namely Lu 2 SiO 5 (LSO), (Lu (1‑ x ) Y x ) 2 SiO 5 (LYSO), LuAlO 3 (LuAP), and Lu (1‑ x ) Y x AlO 3 (LuYAP) activated with Ce and Pr . Besides, the cerium-doped yttrium aluminum (YAP(Ce)) perovskite is a traditional perovskite which has been widely used as the scintillator. ,− …”

Ionizing radiation such as X-rays and γ-rays has been extensively studied and used in various fields such as medical imaging, radiographic nondestructive testing, nuclear defense, homeland security, and scientific research. Therefore, the detection of such highenergy radiation with high-sensitivity and low-cost-based materials and devices is highly important and desirable. Halide perovskites have emerged as promising candidates for radiation detection due to the large light absorption coefficient, large resistivity, low leakage current, high mobility, and simplicity in synthesis and processing as compared with commercial silicon (Si) and amorphous selenium (a-Se). In this review, we provide an extensive overview of current progress in terms of materials development and corresponding device architectures for radiation detection. We discuss the properties of a plethora of reported compounds involving organic−inorganic hybrid, all-inorganic, all-organic perovskite and antiperovskite structures, as well as the continuous breakthroughs in device architectures, performance, and environmental stability. We focus on the critical advancements of the field in the past few years and we provide valuable insight for the development of next-generation materials and devices for radiation detection and imaging applications.

“…The experimental data indicated that the zinc oxide device possesses some increase in its sensitivity to the ionizing radiation as the X-ray effective energy decreases, unlike other types of semiconductor electronic devices frequently used as an X-ray detector [52]. It should be noted that ZnO sensors also have a dual application, such as the application of UV sensors as a scintillator for X-ray detection [53]. In combination with the metal contacts in Au and Ag, the ZnO sensors improve the substance of their luminescence parameters [54].…”

Lithium-ion batteries (LIBs) still need continuous safety monitoring based on their intrinsic properties, as well as due to the increase in their sizes and device requirements. The main causes of fires and explosions in LIBs are heat leakage and the presence of highly inflammable components. Therefore, it is necessary to improve the safety of the batteries by preventing the generation of these gases and/or their early detection with sensors. The improvement of such safety sensors requires new approaches in their manufacturing. There is a growing role for research of nanostructured sensor’s durability in the field of ionizing radiation that also can induce structural changes in the LIB’s component materials, thus contributing to the elucidation of fundamental physicochemical processes; catalytic reactions or inhibitions of the chemical reactions on which the work of the sensors is based. A current method widely used in various fields, Direct Ink Writing (DIW), has been used to manufacture heterostructures of Al2O3/CuO and CuO:Fe2O3, followed by an additional ALD and thermal annealing step. The detection properties of these 3D-DIW printed heterostructures showed responses to 1,3-dioxolan (DOL), 1,2-dimethoxyethane (DME) vapors, as well as to typically used LIB electrolytes containing LiTFSI and LiNO3 salts in a mixture of DOL:DME, as well also to LiPF6 salts in a mixture of ethylene carbonate (EC) and dimethyl carbonate (DMC) at operating temperatures of 200 °C–350 °C with relatively high responses. The combination of the possibility to detect electrolyte vapors used in LIBs and size control by the 3D-DIW printing method makes these heterostructures extremely attractive in controlling the safety of batteries.

Herein, the effect of the postannealing process on the structural properties of nitrogen‐doped Zinc oxide nanostructures (N‐ZnO) synthesized by a single‐step hydrothermal method is reported. Detailed structural and compositional characterizations are performed using X‐ray diffraction (XRD), X‐ray photoelectron spectroscopy (XPS), field emission scanning electron microscopy (FESEM), and energy‐dispersive spectroscopy (EDS). Also, the amount of nitrogen doping has been optimized using different concentrations of the precursor solutions and they are subjected to different postannealing environments. The postannealing process is found to alter the defect structure in ZnO significantly. The samples showing the highest nitrogen doping are further evaluated in detail to know their structural variations. The incorporation of nitrogen into the ZnO structure and the effects of the postannealing process substantially alter the electrochemical characteristics by changing the surface properties of ZnO nanosheets. The effect of these structural variations on the electrochemical performance of ZnO is also explored. Under optimized conditions, the highest conductivity of N‐ZnO nanostructures obtained suggests the material as an outstanding candidate for electrochemical applications.
