Metal halide double perovskites with splendid optical features have been considerably investigated for optoelectronic applications. Herein, a series of Mn2+-doped Cs2NaLuCl6 perovskite crystals were prepared. Via adopting the density functional theory calculation, effect Mn2+ doping on electronic structure compound was discussed. It found that crystal can emit intense blue light from host self-trapped exciton (STE) emission. Excited by 320 nm, STE and emissions simultaneously observed in resulting crystals. Owing to efficient energy transfer Mn2+, polychromatic luminescence final products. Moreover, taking advantage various responses emission intensities temperature, thermometric characteristics investigated, their maximum relative sensitivity is 0.99% K-1, which hardly impacted content. Furthermore, prepared exhibit good X-ray radioluminescence properties, low detection limitation 0.99 μGyair s-1. Additionally, utilizing designed crystal, flexible imaging high resolution 20 lp mm-1 be operated high-temperature environment realized. These results indicated are suitable thermometry imaging.

Flexible and Transparent Phosphonium-Based Metal Halide Glass Scintillators for High-Resolution X-ray Imaging

Chemistry of Materials, Год журнала: 2024, Номер unknown

Опубликована: Авг. 13, 2024

Organic–inorganic hybrid metal halides have recently emerged as promising candidates for X-ray imaging, benefiting from their low-cost, high attenuation coefficient, and light yield. However, achieving transparent scintillators remains extremely challenging, which is required high-resolution imaging in medical industrial detection. Glassy materials typically optical transparency, more importantly, they can be easily processed into different shapes scaled up proportionally large-scale production. Here, large-area, flexible, are developed that ideal properties such emissivity low self-absorption. The obtained glassy exhibit a transmittance of 90% the range 450–800 nm, very imaging. A spatial resolution 22.2 lp·mm–1 detection limit 48.39 nGyair·s–1 were achieved based on optimized perovskite glass scintillators. Additionally, phosphonium-based remarkable stability under continuous illumination. melt-quenching approach also suitable upscaling with excellent reproducibility, addresses critical issues facing commercialization.

Abstract In this paper, X‐ray–induced multicolor long afterglow and photostimulated luminescence from Sr 3 (PO 4 ) 2 : Pr 3+ was reported. The Rietveld refinement results have confirmed the as‐prepared sample pure phase with hexagonal crystal system. And showed an excellent luminescent performance. Under excitation of X‐ray, UVC to red region located at 268, 359, 466, 548, 604.3 685 nm, which can be ascribed f 5 d ‐ H , 1 D P 0 → respectively. strongest emission intensity appeared 468 nm. Furthermore, only 30 s X‐ray irradiation induce 12 h emission, nm still reached 3.71 × 10 cps about 37.1 times stronger than background intensity. particular, relation between 268 good linearity. easily “observed” via visible light. possessed (PSL) under 980 NIR laser PSL circle arrived 1.26 cps, after decay. All these that phosphor phosphor, large potential applications in medical field.
