摘要：

We report the miniaturization of single-photon timing fluorescence lifetime spectroscopy using picosecond diode laser excitation and liquid light guide collection of different time-correlated signals in a multiplexed arrangement. Liquid light guide coupling permits multiple channels of fluorescence decay information with respect to wavelength, polarization, sensor, etc, to be collected simultaneously and eliminates a common source of error in convolution analysis. The instrumental performance is demonstrated in a study of perylene fluorescence quenched by cobalt ions in micelles.
