Recent Progress in Halide Perovskite Radiation Detectors for Gamma-Ray Spectroscopy

Halide perovskites and perovskite related materials for particle radiation detection

“…This journal is © The Royal Society of Chemistry 2022 kite γ-ray detectors has been improving rapidly, and detectors based on inorganic perovskite CsPbBr 3 have demonstrated performances comparable to those of established CdZnTe ternary alloys. [56][57][58][59] A few comprehensive review articles published lately have summarized these recent progress on electromagnetic radiation detectors based on halide perovskite, for example, X-ray detectors, 51,60 γ-ray detectors, 59 and both. 61,62 Recently, significant efforts have been made toward particle radiation detection using halide perovskites, for example for detecting α particles, [63][64][65] β particles, 66 thermal neutrons, 67,68 and fast neutrons.…”

Design Principles of Hybrid Nanomaterials for Radiotherapy Enhanced by Photodynamic Therapy

“…The efficiency of radiative energy transfer strictly depends on the scintillation quantum efficiency, i.e., the light yield (LY), which is usually defined as the number of photons emitted with respect to the fraction of deposited energy and expressed in ph MeV −1 . The LY value depends on several parameters including the type and energy of the ionizing radiation and the photoluminescence quantum yield of the nanoparticle, which can be as large as an increase near to 100% in several types of scintillating nanomaterials [ 99 , 100 , 101 ]. Lastly, the efficiency of the radiative ET is dependent on the concentration of the absorbing moiety, i.e., the PDT agent.…”

Cesium lead bromide semiconductor radiation detectors: crystal growth, detector performance and polarization

“…Spectroscopic gamma detectors have numerous applications spanning from homeland security to medical imaging. 1 Semiconductor-based gamma detectors can provide unmatched energy resolution (ER) as high as 0.1% at 662 keV as in the case of cooled High Purity Ge (HPGe). Cadmium Zinc Telluride (CZT) radiation detectors are currently the only commercially available room-temperature semiconductor detectors, with their superior spectral resolution approaching the performance of cooled HPGe detectors.…”
