• Systematic Studies on Chain Lengths, Halide Species, and Well Thicknesses for Lead Halide Layered Perovskite Thin Films

  Two-dimensional layered perovskite compounds, (CnH2n+1NH3)2(CH3NH3)m−1PbmX3m+1 (n = 2, 3, 4, 6, and 10; X = Cl, Br, and I; m = 1, 2, and 3) were systematically prepared. The influences of the barrier-size, halide species, and well thickness of the perovskite thin films on the quantum confinement structures were investigated. The layered perovskite films showed a strong and clear absorption peak due to excitons confined in inorganic quantum-wells. The exciton peak shifted to lower energy as the halide species was changed from Cl to Br and I. Furthermore, fine multilayer perovskite compound films were prepared by varying the spin-coating conditions.

  二维层状钙钛矿化合物（CnH2n+1NH3）2（CH3NH3）m−1PbmX3m+1（n=2，3，4，6，10；X=Cl，Br，I；m=1，2，3）被系统地制备。研究了钙钛矿薄膜的势垒大小、卤素种类和阱厚对量子限域结构的影响。层状钙钛矿薄膜由于限制在无机量子阱中的激子而显示出强烈而清晰的吸收峰。随着卤素种类从Cl变为Br和I，激子峰向低能量方向移动。此外，通过改变旋涂条件制备了精细的多层钙钛矿化合物薄膜。

  UV-vis spectra of this perovskite single crystal showed a unique structural phase transition as the temperatures varied. The thermoelectric properties of this MAPbI3 single crystal were studied, showing that the Seebeck coefficient of 920 ± 91 μV K−1 almost remained unchanged from room temperature to 330 K and it progressively increased with the increase in temperature and reached 1693 ± 146 μV K−1 at 351

These results demonstrate this class of hybrid organic-inorganic perovskite as a platform to study random lasing with well-defined
