摘要：

Pyrene excimer formation in individual liquid paraffin droplets dispersed in aqueous gelatin matrices was studied by three-dimensional space- and time-resolved fluorescence spectroscopy. The pyrene excimer formation efficiency in the droplets was constant irrespective of the droplet size. The parameters of the excimer formation were determined for each droplet and compared with those observed in bulk pyrene/liquid paraffin solution. The results were discussed on the basis of the depth profiles and the dynamics of pyrene fluorescence in individual liquid paraffin droplets. A distribution equilibrium of pyrene between the oil and the aqueous gelatin was also considered.
