Abstract

Lead halide perovskite single crystals have emerged as promising candidates for high-performance optoelectronic devices because of their superior optoelectronic properties. To date, much literature has reported the fabrication of various perovskite single-crystal structures. However, it still lacks effective rationalization and a comprehensive understanding of the relationship between the structural characteristics and functional properties of the perovskite single crystals, which is of great significance for fabricating perovskite single crystals-based high-performance optoelectronic devices. In this review, we give a comprehensive overview of the synthesis of perovskite single crystals with diverse dimensions, including 0D perovskite quantum dots (QDs), 1D micro/nanowires, 2D micro/nanoplates and single-crystal thin films (SCTFs), and 3D micro/nanoscale single-crystal structures. The relationship between the dimensional structure and properties of the perovskite single crystals is discussed in detail. Dimensional requirements for different optoelectronic applications are systematically summarized. Finally, perspectives on remaining challenges and future opportunities are highlighted.

A systematic understanding of perovskite single crystal is critical for the development of high-performance functional devices. We outline the synthesis strategies, unique characteristics, and optoelectronic applications of perovskite single crystals with diverse dimensions, including 0D perovskite QDs, 1D micro/nanowires arrays, 2D micro/nanoplates arrays and single-crystal films, and 3D micro/nanoscale single-crystal structures, providing guidelines for the application of integrated devices.
