Polymorphism‐Dependent Organic Room Temperature Phosphorescent Scintillation for X‐Ray Imaging

Advanced Materials, Год журнала: 2024, Номер 36(18)

Опубликована: Янв. 25, 2024

Abstract Organic phosphorescent scintillating materials have shown great potential for applications in radiography and radiation detection due to their efficient utilization of excitons. However, revealing the relationship between molecule stacking radioluminescence scintillators is still challenging. This study reports on two phenothiazine derivatives with polymorphism‐dependent phosphorescence radioluminescence. The experiments reveal that significantly affects non‐radiation decay triplet excitons scintillators, which further determines scintillation performance under X‐ray irradiation. These exhibit high radio stability a low limit 278 nGys −1 . Additionally, application these radiography, based excited properties, demonstrated. findings provide guideline obtaining high‐performance by shedding light effect crystal packing organic molecules.

KTb_3−xGd_xF₁₀ Nano‐Glass Composite Scintillator with Excellent Thermal Stability and Record X‐Ray Imaging Resolution

Laser & Photonics Review, Год журнала: 2025, Номер unknown

Опубликована: Янв. 4, 2025

Abstract Scintillators exhibiting both excellent spatial resolution and thermal stability are highly sought after. Herein, by employing a suite of techniques—including phase‐separation‐assisted crystallization, energy transfer, compensation—Tb 3+ ‐doped nano‐glass composite (nano‐GC) scintillators developed with good scintillation performance. The Tb nano‐GC scintillator exhibits an unprecedented enhancement in the integrated intensity X‐ray excited luminescence (XEL) more than five times, as compared Bi 4 Ge 3 O 12 (BGO) crystal. It achieves estimated light yield 54 900 photons MeV −1 sensitivity 635.31 nGy air s . An imaging system based on delivers record 28.7 lp mm at room temperature 28.1 even 500 °C, thanks to stability, namely, preserves original XEL up 300 ≈73% °C. heat resistance excels currently available high‐temperature materials. These attributes, combined robust moisture resistance, position exceptionally promising candidate for used harsh environments.

Much can be learned from the research and development of scintillator crystals for improving scintillation performance glasses. Relying on concept "embedding crystalline order in glass", we have demonstrated that properties Ce3+-doped nanoglass composites (nano-GCs) optimized via synergistic effects Gd3+-sublattice sensitization band-gap engineering. The nano-GCs host a large volume fraction KYxGd1–xF4 mixed-type fluoride nanocrystals (NCs) still retain reasonably good transparency at Ce3+-emitting wavelengths. light yield 3455 ± 20 ph/MeV is found, which largest value ever reported NC-embedded nano-GCs. A comprehensive study given highly selective doping Ce3+ NCs its positive effect properties. favorable influence Y3+/Gd3+ mixing suppression defects accounted by density functional theory borne out experimentally. As proof-of-concept, X-ray imaging with spatial resolution (7.9 lp/mm) employing superior radiation hardness, repeatability, thermal stability designed scintillators bode well their long-term practical applications.
