Abstract :
Perovskite-type organic/inorganic hybrid layered compound (C6H5C2H4NH3)2PbI4 was synthesized. The patterning of (C6H5C2H4NH3)2PbI4 thin films on silicon substrate was realized by the micromolding in capillaries (MIMIC) process, a kind of soft lithography. Bright green luminescent stripes with different widths (50, 15, 0.8 μm) have been obtained. The structure and optical properties of (C6H5C2H4NH3)2PbI4 films were characterized by X-ray diffraction (XRD), UV/Vis absorption and photoluminescence excitation and emission spectra, respectively. It is shown that the organic–inorganic layered (C6H5C2H4NH3)2PbI4 film was c-axis oriented, paralleling to the substrate plane. Green exciton emission at 525 nm was observed in the film, and the explanations for it were given.
