Preparation and Characterization of YAG:Ce Nanophosphor by Cathodic Electrodeposition Method

YAG:Ce nanophosphor was synthesized by a novel method, based on the cathodic electrodeposition from the mixture of bath chloride dissolved in water/ethanol 1:3 solution. First, hydroxide precursors cathodically grown on the steel substrates then, heat treated the hydroxide powder at 1100 °C for 4 h in dry air atmosphere. The obtained oxide product was confirmed by X-ray photoelectron spectroscopy (XPS), Fourier transform infrared (FTIR) spectroscopy, X-ray diffraction (XRD), and scanning electron microscopy (SEM). Broad emission band in the range 500-700 nm was observed in photoluminescence (PL) spectrum of the crystalline YAG:Ce nanophosphor with the maximum intensity at 528 nm. These results revealed that cathodic electrodeposition followed by heat-treatment is a unique method for preparation of YAG:Ce nanophosphor compound.
