  Synthesis and luminescence properties of lead-halide based organic–inorganic layered perovskite compounds (CnH2n+1NH3)2PbI4 (n=4, 5, 7, 8 and 9)

  摘要：

  This paper describes the synthesis and characterization of organic inorganic layered perovskite compounds, (CnH2n+1NH3)(2)PbI4 (n=4, 5, 7, 8 and 9). The effect of the number of carbon atoms on luminescence properties has been examined. Thin films of microcrystalline (CnH2n+1NH3)(2)PbI4 fabricated by spin-coating are highly oriented, with the c-axis perpendicular to the substrate surface. Temperature-dependent optical absorption spectra reveal that (CnH2n+1NH3)(2)PbI4 films (n = 4, 7, 8 and 9) show the structural phase transitions. The excitonic structures of (CnH2n+1NH3)(2)PbI4 vary with the number of carbon atoms of the alkyl chain length. At low temperatures below 100 K, the lowest-energy free-exciton band of (CnH2n+1NH3)(2)PbI4 (n = 7, 8 and 9) split into three fine-structure levels. In contrast to (CnH2n+1NH3)(2)PbBr4 films, (CnH2n+1NH3)(2)PbI4 (n = 7, 8 and 9) shows no triplet exciton emission, but it shows the Stokes-shifted emission from bound excitons. (C) 2011 Elsevier Ltd.

  n-pentylaminium and FA is formamidine), which features the 2D Ruddlesden-Popper type perovskite framework that is composed of the corner-sharing PbI6 octahedra is reported. Significantly, photodetectors fabricated on highly oriented thin films, which exhibit a perfect orientation parallel to 2D inorganic perovskite layers, exhibit a superfast response time up to ≈2.54 ns. To the best of the knowledge, this

  二维杂化钙钛矿由于其独特的结构结构而具有令人着迷的属性，因此在光电检测领域显示出了广阔的前景。但是，基于这种2D系统的大多数检测器具有相对较低的响应速度（≈ms），因此迫切需要开发用于超快光电检测的新候选物。在这里，一种新的有机-无机杂化钙钛矿，（PA）2（FA）Pb2 I7（EFA，其中PA为正戊基铵，FA为甲am），其特征在于2D Ruddlesden-Popper型钙钛矿骨架由角组成。报告了共享的PbI6八面体。重要的是，在高度取向的薄膜上制造的光电探测器表现出与2D无机钙钛矿层平行的完美取向，并具有高达≈2.54ns的超快响应时间。据我所知，这一优异性能赶上了顶级商业材料的性能，并刷新了2D混合钙钛矿光电探测器的新记录。此外，在检测器中还实现了极高的光检测能力（≈1.73×1014 Jones，在≈46µW cm-2的入射功率强度下），相当大的开关比（> 103）和低暗电流（≈10

  The residual strain in 2D Ruddlesden–Popper perovskite films is investigated by X-ray diffraction and atomic force microscopy. Strain relaxation facilitated by the organic spacer cations leads to improved film quality, suppressed recombination, and enhanced device performance under external stress.

  spectroscopy, we also demonstrate that the phase transition in the organic layer couples to the inorganic lattice, impacting PL intensity and wavelength. We take advantage of changes in PL intensity to image the dynamics of this phase transition and show asymmetric phase growth at the microscale. Our findings provide the necessary design principles to precisely control phase transitions in 2D perovskites for
