Optical Spectroscopy of Two-Dimensional Layered (C(6)H(5)C(2)H(4)-NH(3))(2)-PbI(4) Perovskite

Opt Express. 2010 Mar 15;18(6):5912-9. doi: 10.1364/OE.18.005912.


We report on optical spectroscopy (photoluminescence and photoluminescence excitation) on two-dimensional self-organized layers of (C(6)H(5)C(2)H(4)-NH(3))(2)-PbI(4) perovskite. Temperature and excitation power dependance of the optical spectra gives a new insight into the excitonic and the 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.
