Abstract Two-dimensional lead halide perovskites have demonstrated their potential as high-performance scintillators for X- and gamma-ray detection, while also being low-cost. Here we adopt lithium chemical doping in two-dimensional phenethylammonium bromide (PEA) 2 PbBr 4 perovskite crystals to improve the properties add functionalities with other radiation detections. Li is confirmed by X-ray photoemission spectroscopy scintillation mechanisms are explored via temperature dependent...
Two-dimensional (2D) hybrid lead halide perovskites are potential candidates for high light yield scintillators as they have small band gaps between 3 and 4 eV large exciton-binding energy. Here, we discuss the scintillation properties from a total of 11 organic/inorganic perovskite crystals with two already reported crystals, (PEA)2PbBr4 (EDBE)PbBr4. Their photoluminescence X-ray luminescence (XL) spectra dominated by narrow broad emissions, correspond to free exciton self-trapped exciton,...
Commensurate Lithium doping of two-dimensional lead halide perovskites leads to improved scintillation properties, with enhanced light yield, narrower energy resolution, higher radiation hardness and faster decay.
Two-dimensional hybrid-organic-inorganic perovskite (2D-HOIP) lead bromide crystals have demonstrated great potential as scintillators with high light yields and fast decay times while also being low cost solution-processable materials for wide energy radiation detection. Ion doping has been shown to be a very promising avenue improvements of the scintillation properties 2D-HOIP crystals.

Demonstration of how rational design affects self-trapped emission characteristics and scintillation properties in mechanochemically synthesised caesium copper halide perovskites.
Temperature- and dose-dependent measurements of X-ray luminescence (XL) in various perovskite single crystals are reported. For methylammonium lead halide perovskites (MAPbX3, MA = methylammonium, X Cl, Br, or I), the quenching temperature XL intensities shifts to lower temperatures sequence from Cl I. This is strongly affected by decrease thermal activation energy ΔEq 53 ± 3 6 1 meV. We replace MAPbBr3 with Cs observe that even temperature. But unlike MAPbX3 perovskites, CsPbBr3 now...
Among the two-dimensional hybrid organic-inorganic perovskites, PEA2PbBr4 is one of best scintillators combining high light yield and fast nanosecond decay time. However, it has limited sensitivity to X-ray positron emission tomography because insufficient mass density effective atomic number. In this article, we show that exchanging halide from bromide iodide allows shorten absorption length as much two times for energies. We present a detailed study on scintillation properties self-grown...
Quantum-well (QW) hybrid organic-inorganic perovskite (HOIP) crystals, e.g., A2PbX4 (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, BPbX3 (B MA). Inserting 3D into QW structures resulted in new structures, namely A2BPb2X7 and they may have promising optical scintillation properties toward higher mass density fast timing scintillators. In this article,...

Lead halide perovskite (LHP) nanocrystals (NCs) have recently attracted attention due to both their high quantum yield and potential for X-ray imaging applications. In this paper, we investigated the scintillation properties of three different LHP NCs; CsPbBr3, FAPbBr3, CsPbI3. The featured NCs exhibited excited luminescence (XL) at cryogenic temperatures. While FAPbBr3 CsPbI3 display thermal quenching, CsPbBr3 show negative quenching XL temperatures, with a light 24,000 ± 2,100 photons/MeV...
