Ultrafast Temperature Jump Study of Energy Transfer in Dye-Doped Polymer Films
Ultrafast laser spectroscopy of condensed matter samples containing dyes functioning as molecular optical heaters and optical thermometers is developed. A known amount of heat is deposited in a molecular solid sample and the temperature is accurately measured. This technique, termed ultrafast …
