Synthesis and Characterization of YAG Nanostructure

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 grown on the steel substrates then, heat treated the hydroxide powders at 850 °C for 4 h in dry air atmosphere. The formation of crystalline YAG nano powder 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.
