  摘要：

  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。

  330.4 K (9.7 J K −1 mol −1 ). The transition entropies indicated that the phase transitions are of the order-disorder type. They are interpreted with three possible models involving the methylammonium ions disordered with respect to the orientation of the C-N axis itself and around the C-N axis. The infrared line width of the v 12 vibration of the methylammonium ion depended markedly on the temperature

  optoelectronic properties. It is proved that the MAPbCl3 single crystal is more excellent than its polycrystalline counterpart because of its fewer defects and grain boundaries. When referring to a single crystal, the crystal orientation or crystal structure anisotropy is an inevitable topic, because structure anisotropy can affect or decide the optoelectronic properties of single crystals. In this study

  杂化钙钛矿MAPbCl 3由于其出色的光电性能，被认为是可见光紫外光电探测器中最有前途的候选材料之一。事实证明，由于MAPbCl 3单晶的缺陷和晶界较少，因此其性能优于多晶MAPbCl 3单晶。当提及单晶时，晶体取向或晶体结构各向异性是不可避免的主题，因为结构各向异性会影响或决定单晶的光电性能。在这项研究中，立方和三角棱镜MAPbCl 3从混合溶液中成功生长出具有（100）和（110）晶面的单晶。研究了晶体的生长过程，晶体结构和光吸收。此外，通过在（100）和（110）平面上使用Au叉指电极制造金属-半导体-金属（MSM）光电探测器，通过比较光电流，响应度，外部量子效率和检测率，探索了光电各向异性。根据晶体结构和计算出的电荷密度，揭示了MAPbCl 3单晶中的光电各向异性。

  CH3NH3PbX3 (X = Cl, Br, I) perovskites were prepared by a self-organization processes using different precursor solutions. The XRD analysis indicates the formation, at room temperature, of a tetragonal structure (space group I4/mcm) for X = I, of a cubic structure (space group Pm (3) over barm) for X = Br, and of centro-symmetric cubic structure (space group Pm3m) for X = Cl, respectively. The structural analysis revealed the formation of CH3NH3Cl as secondary phase in the Cl-containing system. The morphological investigation revealed the formation of rhombo-hexagonal dodecahedra crystallite for X = I, Br, whereas cube-like aggregates were observed for X = Cl. The thermogravimetric analysis performed in air did not reveal any loss until 250 degrees C for X = I and 300 degrees C for X = Br, respectively, whereas the differential thermal analysis (DTA) detected two endothermic thermal events (at 336 and 409 degrees C) for X = I and one only (379 degrees C) for X = Br, respectively. The infrared spectra (IR) of the powders conformed to the 3-fold symmetry of the methylammonium ion which rotates around the C-N axis. Optical absorption measurements indicated that the CH3NH3PbX3 systems behave as direct-gap semiconductors with energy band gaps of 1.53 eV for X = I, 2.20 eV for X = Br, and 3.00 eV for X = Cl, respectively, at room temperature. The direct-gap semiconductivity for X = I and X = Br was confirmed by the photoluminescence emission measurements, whereas the compound for X = Cl is inactive. I-containing powders were dissolved in an organic solvent (dimethyl-formamide, DMF). The dispersion (100-300 mu L) was dropped on glassy substrates on which thick films were obtained by spin-coating and thermal treatment at 120 degrees C for ca. 5 min. The preparation of the layers was performed in air at room temperature.

  The temperature-dependent structure of crystalline methylammoniumtrihalogenoplumbates (II)—CH3NH+3PbX−3 (X=Cl, Br, I)—as determined by x-ray diffraction, is compared with measurements of the temperature-dependent complex permittivity at frequencies of 50–150 GHz. The dielectric measurements reveal a picosecond relaxation process which corresponds to a dynamic disorder of the methylammonium group in the high-temperature phases of the trihalogenoplumbates.
