Mixed Yttrium–Ytterbium–Erbium Schiff Base Complex as a Model Precursor for Mixed Nanosized Rare Earths Oxides

Novel mixed rare-earth complex of Y, Yb and Er with Schiff base ligand PL–AlaK was synthesized and characterized in detail by a wide spectrum of analytic techniques such as UV–Vis spectroscopy, Fourier-transform infrared spectroscopy, elemental analysis (CHNS–O) and energy dispersive spectroscopy (EDS) measurements. Thermal properties of Y–Er–Yb–PL–Ala complex were studied using simultaneous thermal analysis. Product of thermal decomposition, nanosized mixed oxide was characterized by EDS, X-ray powder diffraction and by transmission electron microscopy. The approach may be used for various template syntheses of optical active nanomaterials, for assembling of nanocomposites or synthesis of various doped REs nanomaterials.
