In this regard, lead-free metal halide perovskites and hybrids with efficient charge extraction and high photoluminescence quantum efficiencies (PLQEs) for X-ray detectors have received increasing interests 27, 28, 29, 30, 31, 32, 33. However, the toxicity of lead in these halide perovskites might limit their potential commercial applications. X-ray scintillators have also been developed using highly emissive metal halide perovskite nanocrystals 21, 22, 23, 24, 25, 26. Recently, lead halide perovskites, such as CsPbBr 3 and MAPbBr 3, have been demonstrated in direct X-ray imaging, owing to their strong X-ray absorption and efficient conversion to charge carriers 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20. Therefore, searching for low-cost, high-performance scintillation materials is still of great scientific and practical interest. While various types of materials have been used for X-ray scintillators, there are still many issues and limitations to existing organic and inorganic scintillation materials, for example, rigorous conditions required for the preparation of inorganic crystals and their hygroscopicity, anisotropic scintillation of organic crystals, low light yields in plastics, and so on 5, 6, 7, 8, 9. ![]() Scintillators, with the ability to convert ionizing radiation into visible photons, have received extensive attention in recent years, as they can be used as radiation detectors for radiation exposure monitoring, security inspection, space exploration, and medical imaging 1, 2, 3, 4. X-ray imaging tests show that scintillators based on (C 38H 34P 2)MnBr 4 powders provide an excellent visualization tool for X-ray radiography, and high resolution flexible scintillators can be fabricated by blending (C 38H 34P 2)MnBr 4 powders with polydimethylsiloxane. Its X-ray scintillation properties are characterized with an excellent linear response to X-ray dose rate, a high light yield of ~ 80,000 photon MeV −1, and a low detection limit of 72.8 nGy s −1. This zero-dimensional organic metal halide hybrid exhibits green emission peaked at 517 nm with a photoluminescence quantum efficiency of ~ 95%. Here, we report highly efficient X-ray scintillators with state-of-the-art performance based on an organic metal halide, ethylenebis-triphenylphosphonium manganese (II) bromide ((C 38H 34P 2)MnBr 4), which can be prepared using a facile solution growth method at room temperature to form inch sized single crystals. Throughout, the author does not offer complicated derivations of equations but, instead, presents useful equations with practical results.Scintillation based X-ray detection has received great attention for its application in a wide range of areas from security to healthcare. The section on the role of defects in energy transfer and scintillation efficiency will be of special interest. The book then discusses the complicated mechanisms of energy conversion and transformation in inorganic scintillators. This unique work first defines the fundamental physical processes underlying scintillation and governing the primary scintillation characteristics of light output, decay time, emission spectrum, and radiation hardness. Written by distinguished researcher Piotr Rodnyi, this volume explores this challenging subject, explains the complexities of scintillation from a modern point of view, and illuminates the way to the development of better scintillation materials. Now, a world leader in the theory and applications of scintillation processes integrates the latest scientific advances of scintillation into a new work, Physical Processes in Inorganic Scintillators. ![]() However, until now there have been no books available that address in detail the complex scintillation processes associated with these new developments. Demand continues for new and improved scintillation materials for a variety of applications including nuclear and high energy physics, astrophysics, medical imaging, geophysical exploration, radiation detection, and many other fields. New scintillation materials have been investigated, novel scintillation mechanisms have been discovered, and additional scintillator applications have appeared. During the last ten to fifteen years, researchers have made considerable progress in the study of inorganic scintillators. ![]()
