摘要：

A time-dependent fluorescence Stokes shift study of the LDS 751 (styryl 8) dye molecule in ethanol solution is presented. Fluorescence intensity curves were recorded with sub-picosecond time resolution at various wavelengths using the fluorescence upconversion method. From the experimental curves, time-resolved fluorescence spectra have been reconstructed, allowing the calculation of the spectral shift correlation function c(t) = [vBAR(t) -vBAR(infinity)]/[vBAR(0) -vBAR(infinity) ]. We find c(t) of LDS 751 in ethanol at room temperature to be well described by a monoexponential function with a 1/e time of 5 +/- 1 ps.
