Summary: Halide perovskites (HPs) have recently emerged as competitive scintillators for X-ray detection and imaging. Their tunable structure and versatile chemical compositions provide advantages over traditional inorganic scintillators. Efforts have been made to expand the inventory of HP scintillators and regulate material properties, with a focus on improving light yield and X-ray imaging performance.

Summary: This article describes the synthesis and characterization of an inorganic mixed-cation double halide perovskite. Single crystals and nanocrystals of the perovskite were created via hydrothermal reaction and mechanosynthesis, respectively. A computational model was developed to predict the X-ray diffraction pattern of the material. The photoluminescence spectra showed self-trapped exciton emission, and nanocomposites exhibited bright radioluminescence due to their optical transparency.

Summary: Lead-free metal halide materials, such as Cs3Cu2Br5, have gained significant attention as promising X-ray scintillators. Cs3Cu2Br5 exhibits self-trapped exciton emission, large Stokes shift, and negligible self-absorption. With a unique temperature-induced reversible fluorescence discoloration phenomenon, Cs3Cu2Br5 shows potential to be a thermochromic fluorescence material.

Summary: We present the development of mixed-halide perovskite (CsPbClx Br(1-x)) nanocrystal scintillators for X-ray detection applications. The effect of varying the halide composition on peak emission and light yield is discussed, with CsPbBr3 materials showing the highest light yield. These perovskite nanocrystals were successfully loaded into PMMA at 2% mass weighting and their responses were compared to colloidal dispersions. The PMMA-CsPbBr3 composites outperformed materials containing Cl- anions in terms of radioluminescent light yield, decay response, and X-ray sensitivity.

Summary: The study demonstrates the improved efficiency of 4H-SiC Schottky barrier diodes-based detectors by optimizing the thickness of thermal neutron converters. By utilizing Monte Carlo codes, the optimal thickness of thermal neutron converters using (LiF)-Li-6 and (B4C)-B-10 materials were determined, achieving thermal neutron efficiencies of 4.67% and 2.24% respectively.

Summary: In this study, a Cu+ and Al3+ co-doped ZnS scintillator was designed for X-ray detection. The prepared scintillator showed a high steady-state light yield (53,000 photons per MeV) upon X-ray irradiation, which is 5.3 times higher than that of the commercial Bi4Ge3O12 (BGO) scintillator. It was also employed as a scintillator to construct an indirect X-ray detector with superior spatial resolution and persistent stability under visible light interference.

Summary: Novel boron-loaded deuterated liquid scintillators (BLDLS) were prepared and characterized for the first time to investigate the performance of a detector sensitive to both fast and thermal neutrons for future neutron spectroscopy measurements. Results showed that loading the scintillators with boron slightly decreased pulse-shape discrimination performance and led to a reduction in relative light yield compared to the unloaded deuterated scintillator. Additionally, BLDLS exhibited a higher relative detection efficiency for shielded neutron sources, making them suitable for missions related to detecting illicitly-trafficked special nuclear material.

Summary: This study presents a unique strategy using starlike block copolymers as nanoreactors to synthesize uniform lead chalcogenide nanoparticles with tailored sizes, surface chemistry, near-infrared optoelectronic properties, and enhanced stability. The resulting nanoparticles show progressive red shift in NIR absorption and emission, and remarkably improved stability against air exposure compared to conventional ligand-capped counterparts. This approach can be extended to synthesize functional nanoparticles and investigate their physical properties, self-assembly, and applications.
