有机-无机杂化钙钛矿材料由于其优异的光电性能在太阳能、照明、光电探测器和激光器等领域有着广泛的应用，引起了人们的广泛关注。这些杂化材料的合理设计是优化其在钙钛矿基器件中性能的关键因素。在此，提出了一种机械化学方法作为一种高效，简单，可重复的方法制备四种类型的混合钙钛矿，这是获得了大量的多晶粉末，具有高纯度和优异的光电性能。合成了两种典型的三维（3D）钙钛矿（MAPbI（3）和FAPbI（3）），以及二维（2D）钙钛矿（Gua（2）PbI（4））和“双链”一维（1D）钙钛矿（GuaPbI（3）），其结构通过X射线衍射进行了阐明。
Organic-inorganic hybrid perovskites have attracted significant attention owing to their extraordinary optoelectronic properties with applications in the fields of solar energy, lighting, photodetectors, and lasers. The rational design of these hybrid materials is a key factor in the optimization of their performance in perovskite-based devices. Herein, a mechanochemical approach is proposed as a highly efficient, simple, and reproducible method for the preparation of four types of hybrid perovskites, which were obtained in large amounts as polycrystalline powders with high purity and excellent optoelectronics properties. Two archetypal three-dimensional (3D) perovskites (MAPbI(3) and FAPbI(3)) were synthesized, together with a bidimensional (2D) perovskite (Gua(2)PbI(4)) and a "double-chain" one-dimensional (1D) perovskite (GuaPbI(3)), whose structure was elucidated by X-ray diffraction.
