为了获得块状立方相CH 3 NH3 PbI 3，用氯苯调节CH 3 NH3 PbI 3 γ-丁内酯溶液，使其在室温下具有高饱和溶解度，并且在60 ℃下具有高晶体产率。结果表明，首次采用混合溶剂法在60 ℃（略高于四方-立方相转变温度）下成功合成了块状立方相CH 3 NH3 PbI 3单晶。
To obtain bulk cubic CH3NH3PbI3, chlorobenzene was employed to regulate the CH3NH3PbI3 gamma-butyrolactone solution with high saturated solubility at room temperature and a high yield of crystal at 60 degrees C. As a result, bulk cubic CH3NH3PbI3 single crystal was successfully synthesized for the first time in mixed-solvent method at 60 degrees C, which is a little higher than the tetragonal-cubic phase inversion temperature.
