Optical spectroscopy of two-dimensional layered $(C_6{H}_5{C}_2{H}_4-N{H}_3{)}_2-Pb{I}_4$ perovskite

Abstract

We report on optical spectroscopy (photoluminescence and photoluminescence excitation) on two-dimensional self-organized layers of $(C_6{H}_5{C}_2{H}_4-N{H}_3{)}_{2}Pb{I}_4$ perovskite. Temperature and excitation power dependance of the optical spectra gives a new insight into the excitonic and phononic properties of this hybrid organic/inorganic semiconductor. In particular, exciton-phonon interaction is found to be more than one order of magnitude higher than in GaAs QWs. As a result, photoluminescence emission lines have to be interpreted in the framework of a polaron model.
