Y3A5O12:Cr3+ nanophosphor was synthesized by cathodic electrodeposition method. During the preparation procedure, hydroxide precursors were deposited on the surface of cathode via electrochemical reaction and then the final product was achieved by heat treatment of obtained powder at 1100 °C for 4 h. The structure and properties of the obtained product were investigated by various analysis methods such as X-ray diffraction (XRD), Fourier transform infrared (FTIR) spectroscopy, photoluminescence spectroscopy (PL), scanning electron microscopy (SEM) and N2 adsorption-desorption analysis. The XRD patterns of the synthesized YAG: Cr product, were in good match with the pure Y3Al5O12 phase and the absence of any other impurities indicates the transformation of Cr3+ ions into the host matrix (YAG). In the emission spectrum of prepared material, a broad emission containing four pronounced bands at 685, 695, 710 and 725 nm was observed that indicates the presence of Cr3+ ions in the final product and further confirmed the formation of desired oxide product (YAG:Cr). The results of our studies showed that cathodic electrodeposition is a practical and highly efficient method for preparation of Y3A5O12:Cr3+ nanophosphor compound.
