Zinc oxide and ZnO:Ag nanopowders were synthesized in gelatine media, at different calcination temperatures. The obtained powders were characterized using x-ray diffraction (XRD), transmission electron microscopy (TEM), and UV-visible techniques. XRD patterns revealed that all the prepared samples have hexagonal (wurtzite) structures. A new peak (Ag2O) appeared at 900˚C and doping did not happen up to 1100˚C. TEM images show that the average sizes of ZnO particle samples are 30-60 nm for different calcination temperatures. UV-vis spectroscopy indicat that there is a small red shift in the absorption edge in Ag doped ZnO, by increasing the calcination temperature. Also the antibacterial property of the prepared nanopowders were studied and compared to ZnO micropowder
