Abstract
Third-order optical nonlinearity around the exciton resonance in (C6H1 3NH3)(2)PbI4 was measured using time-integrated and spectrally-resolve d four-wave-mixing (FWM) techniques. For excitation below the exciton resonance, biexciton contribution to the FWM signals was observed. The dephasing energy of the biexcitons was estimated to be larger than 10 meV.
