Abstract
A facile one-pot method is developed to produce bifunctional magnetic-fluorescent polyvinylpyrrolidone (PVP) film with excellent superparamagnetism and stable optical property. The optical and magnetic properties and the morphology of the produced PVP film are investigated by fluorescence spectrometry, vibrating sample magnetometer and scanning electron microscopy. The magnetic nanoparticles and the dye molecules are incorporated into the PVP film networks through covalent linkages and the obtained magnetic-fluorescent PVP film exhibits highly stable superparamagnetism and fluorescent property. This facile preparation method can be extended to the fabrication of oxides-doped fluorescent PVP films.
