Highly luminescence europium oxyfluoride (EuOF) nanoceramics with great surface were synthesized by thermal decomposition of Eu(OCC(CH3)3CHCOC3F7)3 (Eu(FOD)3) nanostructures as precursor at 400 °C and ambient atmosphere without adding external additive. Eu(FOD)3 nanostructures were prepared by a sublimation method at various temperatures and the effect of sublimation temperature on morphology and size of products was investigated. The as-prepared Eu(FOD)3 nanostructures were characterized by a field emission scanning electron microscope (FESEM), Fourier transform infrared (FT-IR), energy dispersive X-ray spectroscopy (EDS) and X-ray diffraction pattern (XRD). The minimum of sublimation temperature was 170 °C and the product obtained in this condition was chosen as a desired precursor to synthesize of EuOF nanoparticles. The as-prepared EuOF nano-sized ceramic was characterized by using FESEM, FT-IR, EDS, XRD and a transmittance electron microscope (TEM). The optical emission of EuOF nanoceramics was characterized by photoluminescence spectrum (PL).
