ZnO/ZnAl2O4 nanocomposite films were synthesised by ultrasonic spray pyrolysis (USP) by extracting Al2O(SO4)(2) oxide with zinc chloride hydrate in deionised water. The sample was then subjected to heat treatment at 650 degrees C and 700 degrees C for 1 h, which led to the formation of the spinel oxide (ZnAl2O4) andwurtzite (ZnO) phases. Al-2(SO4)(3)center dot 18H(2)O salt was transformed into aluminum oxide sulfate Al2O(SO4)(2), which is an intermediary decomposition product, by calcination at 795 degrees C for 3h. The structures of the synthesised ZnO/ZnAl2O4 films were confirmed by XRD, FTIR, and X-ray photoelectron spectroscopy (XPS). XPS spectra of the major Zn, Al, and O photoelectron lines and the major X-ray induced Zn LMM Auger lines for ZnO/ZnAl2O4 are presented.
