摘要：

Steady-state fluorescence spectra and time correlated single-photon counting measurements were performed on samples of poly(vinyl alcohol), poly(vinyl acetate) and their blends in different proportions (9/1, 1/1 and 1/9) containing fluorescein and/or anthracene probes. The interface thickness, the surface to volume ratio of microdomains and the heterogeneity of the samples were determined from those measurements.
