Photoinduced dynamics of prussian blue type cyanide

Charge and lattice dynamics has been investigated for Na0.79Co[Fe(CN)6]0.902.9H2O film at 300 K by means of the time-resolved x-ray diffraction apparatus coupled with the in situ time-resolved absorption measurement. We observed an uniform lattice expansion whose relaxation time is ∼ 40 ns. Based on...

Summary:Charge and lattice dynamics has been investigated for Na0.79Co[Fe(CN)6]0.902.9H2O film at 300 K by means of the time-resolved x-ray diffraction apparatus coupled with the in situ time-resolved absorption measurement. We observed an uniform lattice expansion whose relaxation time is ∼ 40 ns. Based on the close correlation between the charge and lattice dynamics, the lattice expansion is ascribed to the photo-created charge-transferred Co2+ - Fe3+ state.
