本文报道了一锅溶剂热合成长方体CH(3) nh3 (3)Pbl(3)单晶的方法，并研究了溶液热体系中晶体平面的稳定性。在此基础上，首次发现了特定表面的溶解现象。通过对结晶和溶解过程的细致控制，我们发现温度和时间等反应因素在钙钛矿晶体的结晶过程中起着至关重要的作用。
Here we report a one-pot solvothermal approach to synthesize cuboid shaped CH(3)NH(3)Pbl(3) single crystals and study the stability of crystallographic planes in a solvothermal system. Furthermore, the dissolution phenomenon from specific facets was discovered for the first time. Through careful control of the crystallization and dissolution processes, we found that reaction factors including temperature and time play critical roles in the crystallization process of perovskite crystals.
