Spin-Coating Preparation of Highly Ordered Photoluminescent Films of Layered PbI2-Aminoalkyloxysilane Perovskites

By utilising 3‐aminopropyltrimethoxysilane (APTMOS) cations and PbI2 as the organic and inorganic precursors, respectively, a spin‐coated film of a layered perovskite‐type organic/inorganic derivative of APTMOS‐PbI4 was prepared. The structure of APTMOS‐PbI4 was characterised by X‐ray diffraction (X...

Description
Summary:By utilising 3‐aminopropyltrimethoxysilane (APTMOS) cations and PbI2 as the organic and inorganic precursors, respectively, a spin‐coated film of a layered perovskite‐type organic/inorganic derivative of APTMOS‐PbI4 was prepared. The structure of APTMOS‐PbI4 was characterised by X‐ray diffraction (XRD), UV/Vis absorption and infrared red spectroscopy (IR). The film showed green emission from the excitons of the inorganic layers and a weak blue emission related to the small amount of gel of adjacent APTMOS cations. Furthermore, the significant effect of the size of the inorganic framework on the cross‐linking degree of APTMOS molecules is discussed. (© Wiley‐VCH Verlag GmbH & Co.
