Abstract:

CsPbBr3 single crystals, as a prominent class of all inorganic perovskite semiconductor materials, have attracted considerable research interest due to their remarkable properties including high density, high resistivity, and excellent charge carrier transport capabilities. These advantages equip them with great potential for applications in various cutting edge fields such as radiation detectors, photodetectors, and light-emitting diodes. However, their further development and practical deployment still face with dual challenges associated with defect control in large volume crystal growth and cost-effective manufacturing. Therefore, this paper comprehensively reviews the research progress of CsPbBr3 single crystal growth via inverse temperature crystallization (ITC). The critical factors affecting crystal quality, including solvent selection, solute concentration regulation, interfacial tension induction mechanism, and solubility-temperature dependence, are systematically analyzed. Effective strategies such as additive incorporation and seed crystal guidance are proposed to optimize crystal growth. Furthermore, the unique advantages of CsPbBr3 single crystals in photoelectric detectors, such as high carrier mobility and long diffusion length, are highlighted. Finally, the development trend of this material in radiation monitoring, medical diagnosis, and other fields is discussed, providing theoretical and technical references for subsequent research.
