摘要: Layered Perovskite compounds expressed by the formula (C6H5C2H4NH3) 2PbX4 (X: halogen) naturally formed a dielectric quantum well structure in their spin-coated films. Strong exciton absorption and sharp photoluminescence from the exciton were observed in the spin-coated films even at room temperature; exciton absorption and emission bands of the layered Perovskite compounds were located at 3.65 eV and 3.57 eV for X= Cl, 3.08 eV and 3.05 eV for X= Br, and 2.41 eV and 2.38 eV for X= I, respectively, Using the combination …
