“…Therefore, toluene can take a longer time to influence the crystallization process until all the solvents evaporate completely. It has been reported elsewhere that CsPbBr 3 NCs may have three different structural phases: cubic (Pm-3m), tetragonal ( P 4 mm ), and orthorhombic ( Pnma ) [ [52] , [53] , [54] ]. The crystal structure of CsPbBr 3 at room temperature is orthorhombic, which can transform into tetragonal and cubic structures after heating to 88 °C and 130 °C, respectively.…”

CsPbBr3 exhibits outstanding optoelectronic properties and thermal stability, making it a coveted material for detectors, light‐emitting diodes, and solar cells. Despite observations of ferroelectricity in CsPbBr3 quantum dots, synthesizing bulk ferroelectric CsPbBr3 crystals has remained elusive, hindering its potential in next‐generation optoelectronic devices like optical switches and ferroelectric photovoltaics. Here, a breakthrough is reported: a novel solvothermal technique enabling the growth of ferroelectric CsPbBr3 nanoplatelets with lateral dimensions in the tens of micrometers. This represents a significant step toward achieving large‐area ferroelectric CsPbBr3 crystals. Unlike traditional methods, this approach allows for growth and crystallization of CsPbBr3 in alcohol solutions by enhancing precursor solubility. This study confirms the ferroelectric nature of these nanoplatelets using second harmonic generation, electrical characterizations, and piezoresponse force microscopy. This work paves the way for utilizing ferroelectric CsPbBr3 in novel optoelectronic devices, significantly expanding the potential of this material and opening doors for further exploration in this exciting field.
