Abstract

As a kind of interesting transparent conductive material which is necessary for obtaining sputtering target and photo catalyst , Ga doped ZnO (ZnO: Ga , G ZO) powders were prepared by sol gel successfully. The influence of gel calcining temperature on photoelectric of sputtering target and photocatalytic properties of powders was investigated in detail at the first time T he measurement results show GZO has a hexagonal wurtzite structure. All of GZO powders have good conductivity, absorption in UV wavelength range and photocatalytic activity. GZO which is got when the gel was calcined at 400℃ has the best photoelectric properties and photocatalytic activity under UV light radiation. These results affords research base for the application of GZO in photo electron and environmental depollution fields.
