Novel method for hit-position reconstruction using voltage signals in plastic scintillators and its application to Positron Emission Tomography

, 2014
Currently inorganic scintillator detectors are used in all commercial Time of Flight Positron Emission Tomograph (TOF-PET) devices. The J-PET collaboration investigates a possibility of construction of a PET scanner from plastic scintillators which would

Deformation‐Induced Formation of Stray Grains in Additive Manufacturing of Single Crystals

Advanced Science, EarlyView.
Stray grain formation severely limits the additive manufacturing of single‐crystal alloys. By integrating in situ synchrotron techniques, ex situ characterization, and multi‐scale multi‐physics modeling, the authors reveal that stray grains originate from dislocations at the solid‐liquid interface, rather than thermal supercooling in conventional ...

Large‐Scale In Situ Formation Perovskite Quantum Dots/Elastomer Composite for High‐Performance White Light‐Emitting Diodes

Advanced Science, EarlyView.
A solvent‐free, open‐mill shear protocol nucleates 2.6 nm CsPbBr3 QDs uniformly within brominated butyl rubber. The emitters showed 91% PLQY, 1189 ns lifetime, and > 90% retention after 30‐day ambient storage and water immersion, respectively. Board‐to‐board forms 17 × 17 cm2 flexible films for 132% NTSC white LEDs, scintillators, and stretchable ...

Tb3+‐Doped Glass‐Ceramic Scintillating Plates and Fibers for X‐Ray Imaging and Flexible Detection

Advanced Science, EarlyView.
A Tb3+‐doped glass‐ceramic scintillator, with controlled Ba2GdF7 nanocrystal precipitation, was developed through a rational design strategy guided by phase diagrams and molecular dynamics simulations. The obtained material exhibits a high light yield of 41 800 photons/MeV (418%/BGO), a spatial resolution of 25.3 lp/mm, and exceptional thermal ...
