摘要: 由于出色的高能射线解析能力和优秀的环境适应性,全无机卤化物CsPbBr3吸引了众多研究者的关注。然而由于结构相变和热应力的存在,大尺寸CsPbBr3晶体生长过程中容易产生应力,从而导致晶体表面出现裂纹、亚晶界或孪晶等缺陷,严重影响其性能。目前大尺寸高质量CsPbBr3晶体仍然无法通过有效的手段进行批量化生产,因此开展大尺寸CsPbBr3晶体的生长与性能研究具有重大理论意义和实际价值。本文简要综述了CsPbBr3晶体的基本性质、制备方法及研究进展,主要讨论了垂直布里奇曼法生长CsPbBr3晶体的影响因素,并对高质量CsPbBr3晶体的生长提出了新的思路。

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.
