An attempt to incorporate a representative laser dye, p-terphenyl, into the layered organic-inorganic perovskite structure was made. From PbX2 (X = Cl, Br) and the corresponding 4.4"-bis(2-aminoethyl)-p-terphenyl (AETP) hydrogen halide salt (AETP-2HX), two kinds of AETP-PbX4 crystals were prepared, and their structural and optical properties were investigated. Emission color of the crystals was fluorescent blue for X = Cl, while phosphorescent orange for X = Br, suggesting different emission processes dependent on the different energy levels of PbX4 perovskite layers.
