We prepared fluorescent dye-doped microspheres from ferroelectric copolymer, poly(vinylidene fluoride-trifluoroethylene)(PVDF-TrFE), by self-assembly at the interface between acetone and water. The resultant dye-doped microspheres exhibits whispering gallery mode (WGM) photoemission upon irradiation to focused laser beam.
