Abstract: All-inorganic halide crystal CsPbBr3 has gained significant attention due to its outstanding high-energy ray resolution capability and excellent environmental adaptability. However, due to the presence of structural phase transitions and thermal stresses, stress is prone to arise during the growth process of large-sized CsPbBr3 crystals, leading to defects such as cracks on the crystal surface, subgrain boundaries and twin crystals. These defects have severely impact on the performance of CsPbBr3 crystals. Currently, large-sized high-quality CsPbBr3still can't be mass-produced through effective means, restricting its further application. Hence, conducting research on the growth and performance of large-sized CsPbBr3 crystals holds great theoretical significance and practical value. This paper briefly summarizes the fundamental properties, crystal preparation methods and research progress of CsPbBr3 crystals, mainly discussing the influencing factors of the vertical Bridgman growth method, and proposing novel optimization ideas for the growth of high-quality CsPbBr3 crystals.
