Organic-inorganic layered perovskite compounds have been attracting attention as optical materials because they exhibit excellent light absorption and emission properties. By introducing optically active amines, they exhibit circular polarization properties such as circular dichroism. In this study, we fabricated two-dimensional perovskite nanoparticles with optically active amine and evaluated their circular polarization properties. The nanoparticles showed exciton absorption at 425 nm and fluorescence at 438 nm. CD was also appeared at exciton absorption region.
