The vanadium tungsten oxide ceramics target of the RF sputtering system was prepared by the conventional mixed oxide method. The starting materials were V 2 O 5 W. Those materials were weighed according to the composition of the V 2 n W n O 5 the weight ratio of irconia ball to powder in the mill was 11 and ethyl alcohol was used as a
