Optical Properties of Poly (acrylonitrile-co-vinyl acetate)/Fluorescent dye Nanocomposites

Fluorescent nanofibers from Poly (acrylonitrile-co-vinyl acetate) [P (AN-co-VAc)] and fluorescent dye are prepared by electrospinning process. The structural and optical properties of nanofibrous studied by optical microscopy and photoluminescence spectrometer. The optical microscopy observations confirmed that nanofibrous structure wereformed in electrospinning process. Also from photoluminescence investigations it concluded that the fluorescence intensity is a function of dye concentration and in high values of dye concentrations quenching effect occurs. Thesenovel electrospun nanostructures is applicable in many fields such as optical sensing.
