Synthesis and characterization of highly luminescent EuOF nanoceramics by using prepared Eu(FOD)3 nanoparticles via sublimation method as precursor

Highly luminescence europium oxyfluoride (EuOF) nanoceramics with great surface were synthesized by thermal decomposition of Eu(OCC(CH3)(3)CHCOC3F7)(3) (Eu(FOD)(3)) nanostructures as precursor at 400 degrees 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 degrees 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). (C) 2015 Elsevier Ltd and Techna Group S.r.l. All rights reserved.
