| 摘 要： | In this letter, poly（vinylidene difluoride） （PVDF）/（Y0.97Eu0.03）2O3 rare-earth nanocomposites were prepared by a simple co-precipitation method, and their morphology, structure, and optical properties were investigated. The scanning electron microscope （SEM） images showed that the （Y0.97Eu0.03）2O3 rare- earth nanoparticles formed 50 nm - 2 μm aggregates in PVDF matrices. X-ray diffraction （XRD） curves indicated the incorporation and structure preserving of （Y0.97Eu0.03）2O3 nanoparticles in PVDF matrices. Photoluminescence （PL） spectra of the nanocomposite showed a characteristic red light emission at 612 nm, which was attributed to the intrinsic emission of （Y0.97Eu0.03）2O3 nanoparticles. Optical band gap （Eg） of the nanocomposite exhibited a decreasing trend with the increase of （Y0.97Eu0.03）2O3 content in PVDF matrices within the experimental dosage range.
