Abstract

Optical response due to the phc to-excited carrier or exciton dynamics in the excited state of a one-dimensional metal complex (Pt(dmg)2) has been investigated by femtosecond pump-probe spectroscopy. Measurements were made under various excitation photon energies within the absorption band which originates from the delocalized electronic states along the 1-D chain. Around the lowest-energy absorption peak, absorption bleaching was found to be larger and its decay faster compared to those in higher-energy region. Furthermore, an induced absorption which is considered to be due to a bi-exciton or relaxed excited state was observed.
