  FA_0.8MA_0.2Sn_xPb_1–xI₃ Hybrid Perovskite Solid Solution: Toward Environmentally Friendly, Stable, and Near-IR Absorbing Materials

  摘要：

  We report the first investigation addressing the synthesis and characterization of the FA(0.8)MA(0.2)Sn(x)Pb(1-x)I(3) solid solution showing a complete solubility of Sn on the Pb-site leading to cubic single-phase materials. The explored composition shows excellent phase stability and absorbance in the near-IR spectral region.

  A mixed-cation 3D lead bromide hybrid perovskite (NMDAP)2FAPb4Br13 is tailored through the localized lattice expansion of 3D FAPbBr3. The resulting perovskite shows a high two-photon absorption coefficient of 60.8 cm MW−1 and exhibits a sensitive near-infrared photoresponse with large on/off ratio (≈104) and favorable stability.
