Electrospun nanofibers of poly(vinyl pyrrolidone)/Eu3+ and its photoluminescence properties

Nanofibers of poly(vinyl pyrrolidone) (PVP)/Eu3+ with diameters of 300–900 nm were prepared by using sol–gel processing and electrospinning technique. The products were characterized by scanning electron microscope (SEM), Fourier transform infrared spectroscopy (FT-IR), and photoluminescence (PL). The results indicated that, Eu3+ was successfully embedded in the one-dimensional hybrid nanofibers, and the PVP/Eu3+ hybrid nanofibers had favorable photoluminescence properties.
