抄録
Fluorescence spectra of β-carotene molecules in ethanol have been measured in a temperature range from 20 K to 240 K. Assuming that dephasing of the system is characterized by slow modulation, we obtained temperature dependence of homogeneous and inhomogeneous broadening widths analyzing an almost linear dependence of the fluorescence peak energy on the excitation energy. Theoretical calculations of fluorescence to Raman scattering intensity ratio using the homogeneous and inhomogeneous widths reproduce well experimental results. It supports that, within a wide temperature range from liquid to solid phases of solvent, the essential feature of the optical dephasing process of the system is characterized by the slow modulation.
