摘要：

Dynamics of the charge-transfer (CT) pairs has been investigated for the cyano-bridged Co2+-Fe3+ particles grown in a hydrophilic cavities of Nation 117 film. We decomposed the differential absorption spectra into the fast and slow components. We ascribed the fast and slow components to the Frank-Condon state and the CT (Co3+-Fe2+) pairs with lattice relaxation, respectively. We found that the lifetime tau(CT) of the pairs at 10 K increases with the absorbed photon density n from tau(CT)approximate to 2 ns to 6 ns, reflecting the attractive interaction between the pairs.
