Preparation and photoluminescence of single conjugated polymer-TiO2 composite nanofibers

► Conjugated polymer PPV-TiO2 nanofibers were prepared by electrospinning. ► The polymer-inorganic interfaces were free of organic surfactants. ► The fluorescence microscopy images showed that the resulting nanofibers exhibited outstanding emission properties. ► No significant differences were observed in photoluminescence spectra of PPV-TiO2 and PPV fibers.
