The fluorescence emission behavior of anthracene (An) wrapt in the fil
m cast from poly (butyl acrylate)/polystyrene composite emulsion prepa
red by seed emulsion polymerization was determined. The result shows t
hat the emission spectra are sensitive to the environment of the probe
An. The volatilization of solvent under film-forming will enhance the
luminous emission. The heat treatment to film will weaken the fluores
cence and shift the signals towards higher frequency.
