Effect of vanadium precursor on dip-coated vanadium oxide thin films

Abstract The effect of chemical substances is reported on the structure, surface morphology, and material properties vanadium oxide thin films. study concentrated effects initial materials (e.g., NH 4 VO 3 , NaVO 2 vanadyl acetylacetonate, ammonium decavanadate) various additives acids, chelate ligand, reduction reagent, tensides). syntheses are based sol-gel chemistry. important aim technique was to optimize conditions such as catalyst solvent for preparation perfect V 5+ -containing layers. other check controllability 4+ /V ratios. control performed in air by using a reducing agent nitrogen atmosphere. atomic bond structures were investigated 51 MAS NMR, IR, UV spectroscopies. supramolecular determined SEM, EDX, GIXRD techniques.
