- •
A facile one-pot method towards the construction of bifucntional magnetic-fluorescent polyvinylpyrrolidone (PVP) film.
- •
The mechanism relies on the chemical reaction between the ring-opened PVP and the magnetic nanoparticles as well as the dye molecules.
- •
The PVP film exhibits excellent superparamagnetism and high optical stability due to the covalent bonding of magnetic nanoparticles and the dye molecules.
- •
The facile method could be extended to other oxides for the preparation of multi-functional composite PVP films.
