Abstract
The excitation dynamics and relaxation characteristics of nile blue in polyvinyl alcohol are studied using the time-delayed four-wave-mixing technique at cryogenic temperatures over its absorption linewidth. Th e roles of electronic transition, nuclear vibration, and the phonon si de-band in the observed decay characteristics of the signal are discus sed.
