Deposition of Yb-Bi thin films was carried out from a nonaqueous solution by using cyclic electrodepositon.During electrodeposition the substrate potential was continuously cycled between two potentials.The effects of several factors including the potential of deposition,time of deposition and sweep rate on the Yb content in the thin films and surface morphology were studied.Experimental results indicate that the amorphous Yb-Bi thin films containing Yb 21.04%～36.36%(mass fraction)can be prepared in 0.10 mol·L-1 YbCl3+0.10 mol*L-1 Bi(NO3)3+0.10 mol·L-1 LiCl+DMSO by controlling deposition conditions of the system.They are black,uniform,metallic luster and adhered firmly to the copper substrates.The films were characterized by X-ray energy dispersive analysis(EDS),scanning electron microcoscope(SEM)and X-ray diffraction(XRD).
