Synthesis and characterization of yttrium aluminum garnet nanostructures by cathodic electrodeposition method

•Pure phase YAG nanostructures were prepared by cathodic electrodeposition method.•YAG nanostructures were synthesized in lower temperature.•Morphology of YAG nanostructures were changed with different currents densities.•Morphology of YAG nanostructures were changed with different bath temperatures.•Current density and bath temperature have prominent effect on the particle size.

Pure nanostructures of yttrium aluminum garnet (YAG) was prepared based on the cathodic electrodeposition method from the mixture of YCl3 and AlCl3 dissolved in water/ethanol solution. At first, hydroxide precursors cathodically were grown on the steel substrates then, the hydroxide powders heat treated at 850 °C for 4 h in dry air atmosphere. The formation of crystalline YAG nanopowder was confirmed by X-ray diffraction (XRD), thermogravimetric analysis (DSC-TGA), scanning electron microscopy (SEM) and Fourier transformed infrared spectroscopy (FT-IR). The results of the SEM showed that applied current density and bath temperature have the prominent effect on the morphology and particle size of the products. The results revealed that cathodic electrodeposition followed by heat-treatment can be used as a facile method for preparation of YAG nanostructures with different morphology.
