Effect of Dual-Organic Cations on the Structure and Properties of 2D Hybrid Perovskites as Scintillators.

Two-dimensional (2D) hybrid organic-inorganic perovskite (HOIP) crystals show promise as scintillating materials for wide-energy radiation detection, outperforming their three-dimensional counterparts. In this study, we synthesized single crystals of (PEABZA)PbBr ( ranging from 0.1 to 2), utilizing phenethylammonium (CHCHCHNH) and benzylammonium (CHCHNH) cations.

Improvement of Light Output of MAPbBr Single Crystal for Ultrafast and Bright Cryogenic Scintillator.

The remarkable brightness and rapid scintillation observed in perovskite single crystals (SCs) become even more striking when they are operated at cryogenic temperatures. In this study, we present advancements in enhancing the scintillation properties of methylammonium lead bromide (MAPbBr) SCs by optimizing the synthesis process. We successfully synthesized millimeter-sized MAPbBr SCs with bright green luminescence under UV light.

ABPbI (A = BA, PEA; B = MA; = 1, 2): Engineering Quantum-Well Crystals for High Mass Density and Fast Scintillators.

Quantum-well (QW) hybrid organic-inorganic perovskite (HOIP) crystals, e.g., APbX (A = BA, PEA; X = Br, I), demonstrated significant potentials as scintillating materials for wide energy radiation detection compared to their individual three-dimensional (3D) counterparts, e.

Lattice Expansion in Rb-Doped Hybrid Organic-Inorganic Perovskite Crystals Resulting in Smaller Band-Gap and Higher Light-Yield Scintillators.

Two-dimensional hybrid-organic-inorganic perovskite (2D-HOIP) lead bromide perovskite crystals have demonstrated great potential as scintillators with high light yields and fast decay times while also being low cost with solution-processable materials for wide energy radiation detection. Ion doping has been also shown to be a very promising avenue for improvements of the scintillation properties of 2D-HOIP crystals. In this paper, we discuss the effect of rubidium (Rb) doping on two previously reported 2D-HOIP single crystals, BAPbBr and PEAPbBr.

Scintillation in (CHCHNH)SnBr: green-emitting lead-free perovskite halide materials.

We report the optical and scintillation properties of (CHCHNH)SnBr with excellent absorption length at 20 keV of 0.016 cm, measured bandgap of 2.51 eV, and photoluminescence lifetime of 1.

Stable and Bright Commercial CsPbBr Quantum Dot-Resin Layers for Apparent X-ray Imaging Screen.

CsPbBr quantum dots (QDs) have recently gained much interest due to their excellent optical and scintillation properties and their potential for X-ray imaging applications. In this study, we blended CsPbBr QDs with resin at different QD concentrations to achieve thick films and to protect the CsPbBr QDs from environmental moisture. Then, their scintillation properties are investigated and compared to the traditional commercial scintillators, CsI:Tl microcolumns, and Gadox layers.
