Sažetak
Specific structure of perovskite compounds provides them with various interesting properties which vary from magnetic and electric properties to magnetic frustration and half-metallicity. Double A2Ni(Te, W)O6 and triple A3(Fe, Co)2(W/Te)O9 (A=Sr, Ba) perovskites have been prepared in nanocrystalline form using a modified aqueous sol–gel citrate route. Solution chemistry synthesis mechanism and synthesized compounds itself have been studied by electrochemical measurements. Structural investigation has been conducted by ambient and in situ X-ray powder diffraction (PXRD), X-ray photoelectron spectroscopy (XPS), transmission electron microscopy (TEM), selected area electron diffraction (SAED), thermogravimetric analysis (TGA) and unpolarized Raman spectroscopy, while their magnetic properties have been determined using SQUID measurements. Similar research has already been done with tellurium- and tungsten- based perovskites. In this research the advances of solution chemistry methods (bottom up approach), namely sol-gel citrate route, over the solid-state routes towards the synthesis of complex perovskite structures will be presented.
