  • 摘要:

    Alkylammonium lead halide compounds were reported to form self-organized perovskite-type crystal structures with the general formula (RNH3) 2PbX4 (R: CnH2n+1-, X: halogen) and to take the multiple quantum well structure. Because of their quantum confinement effect, they exhibit strong and sharp photoluminescence and electroluminescence, and highly efficient nonlinear optical properties. One of the interesting properties of the organic-inorganic perovskite compounds is that they can take in various functional molecules into their organic layer, as an example, we have reported to introduce optically active molecules that have the asymmetric carbon atom into the organic layer in order to construct an optically active quantum well. On the other hand, thickness of the well layer of the compounds can control easily by changing preparation conditions. In this study, we prepared multilayered compounds containing optically active molecules by changing composition of spin-coating solutions. The multilayered compounds showed sufficient photoluminescence from structure which was a little component with lower transition energy. These results showed effective energy transfers from major crystal structures took place on the multilayered systems.
