Abstract

In this work RE-Mo-O gels (RE = Gd, Eu) synthesized by an aqueous sol-gel method with citric acid as a complexing agent. Products were characterized with Fourier transform infrared spectroscopy (FTIR). In order to estimate occurring possible reaction mechanism and optimal annealing temperature the thermal analysis (TGA and DTA) of obtained RE-Mo-O citrate gels was performed. Moreover, the crystallinity, morphological features, and luminescent properties of RE2Mo3O12 powders annealed at different temperatures using X-ray diffraction (XRD), scanning electron microscopy (SEM), and photoluminescence(PL) measurements were also investigated.

Abstract (in Czech)

V této práci byly syntetizovány oxidické gely RE-Mo-O (RE = Gd, Eu) vodnou sol-gelovou metodu s použitím citrátu jako komplexujícího činidla. Byl studován vliv příměsí na krystalizaci RE2Mo2O12 (RE = Gd, Eu) a optimalizována krystalizační teplota. Produkty byly studovány pomocí XRD, SEM a fotoluminescence.
