The ZAO powder was synthesized by chemical coprecipitation. The ZAO ceramic sputtering target materials were fabricated by sintering in air, and ZAO transparent conductive films were prepared by RF magnetron sputtering on glass substrates. XRD proved that such films had an orientation of （002） crystal panel paralleled to the surface of the glass substrate. The average transmittance of the films in the visible region exceeded 80%.展开更多

XRD patterns showed that the main components of the target were barium tetra aluminum sulfide （BaAl4S7）, bariutm sulfide （BaS）, and europium sulfide （EuS）. In the samples, part of the barium and aluminum are formed into barium aluminum oxide （BaAl2O4） with the impurity element of oxygen. The PL characteristic spectra of the target showed the 470 nm blue emission obviously, and the Ba-Al-S thin films also transmitted a purple-blue emission at the position of 440 nm.The results indicated that this method was suitable for the fabrication of the Ba-Al-S：Eu sputtering target.展开更多
