The research aims to develop large-size melt-growth and solution growth-based lead-free inorganic perovskite scintillators for the detection of nuclear radiation. The scintillators have gained attention due to their scintillation properties, ease of preparation, non-hygroscopic nature, and low cost of production. However, challenges in commercial applications include lack of data on pulse shape discrimination, intrinsic energy resolution for gamma rays, timing resolution, detection efficiency, and difficulty in growing large-sized crystals. The proposed method aims to synthesize lead-free perovskite scintillators using the melt-growth method and a low-cost novel phoswich detector of Cs3Cu2I₅ perovskite crystal and CsI(Tl) alkali halide crystal using the solution method. The hypothesis or model will be tested using the GEANT4 simulation toolkit, and the main experiments will be conducted using the Bridgman technique and inverse temperature crystallization. The goal is to address limitations associated with the development of low-cost solution growth-based perovskite scintillators, which could replace neutron detectors in security, medical imaging, and space. The availability of room temperature perovskite scintillators could also boost the manufacturing of radiation survey monitors and dosimeters.
