Abstract
Using femtosecond time-resolved luminescence spectroscopy, we have observed a wave-packet oscillation in an adiabatic potential well associated with a self-trapped exciton (STE). We have investigated the STE luminescence band of a quasi-one-dimensional halogen-bridged platinum complex $[{\mathrm{Pt}(\mathrm{en})}_{2}][{\mathrm{Pt}(\mathrm{en})}_{2}{\mathrm{Br}}_{2}]({\mathrm{ClO}}_{4}{)}_{4}.$ In the time evolution of the luminescence, we have observed an oscillation with a period of about 300 fs. This result shows the formation of a wave packet and its oscillation, which is damped with the time constant of about 430 fs. The STE's have a lifetime of about 5.5 ps at room temperature.
