title: [Preparation of lomefloxacin-Tb3+ nanoparticles modified by PVP via microwave-assistance and its properties of fluorescence].
abstract: Polyvinylpyrrolidone(PVP)-modified LFLX-Tb3+ nanoparticles were prepared by microwave radiation method. The obtained products were characterized by means of SEM, FTIR and fluorescence spectra. The surface-modified LFLX-Tb3+ nanoparticles showed a narrow size distribution and enhanced luminescence property compared with that of the unmodified ones. These results were attibuted to the surface passivation of the LFLX-Tb3+ nanoparticles by the PVP molecules. It is confirmed that the addition dosage of PVP is an important factor in the preparation of the LFLX-Tb3+ nanoparticles. The reasons for luminescence enhancement were discussed.
