The large photo-induced change of reflectivity has been observed in the unique charge separated phase of the Et2Me2Sb[Pd(dmit) 2]2 crystal We observe a clear spectral change due to the disappearance of the charge separated phase by femtosecond photo-excitation in the [Pa(dmit)2] dimer. The dynamics of the photo-excited state depends on the excitation intensity. Obtained results strongly suggest that cooperative effect plays a key role in the photo-excited state of this system, We tentatively classify the observed phenomena as a photo-induced phase transition due to the melting of the charge separation.
