Low-dimensional lead-free perovskite single crystals (SCs) have exhibited great potential in high-energy ionizing radiation detections owing to their outstanding sensitivity and charge transport properties. However, the preparation of chlorine-based SCs is more challenging due low solubility organic solvents acidic solutions. In this work, we report a universal growth strategy hydrochloric acid-assisted temperature lowering for low-dimensional layered CsMnCl3·2H2O SCs. Compared with prepared by solution evaporation crystallization, centimeter-sized were achieved ultrahigh crystal quality, showing very small full width at half-maximum 0.02° plane (002).
