Characterisation of porous doped ZnO thin films deposited by spray pyrolysis technique

Al or Sn doped ZnO films were deposited by spray pyrolysis using aqueous solutions. The films were deposited on either indium tin oxide coated or bare glass substrates. ZnCl 2, AlCl 3 and SnCl 2 were used as precursors. The effect of ZnCl 2 molar concentration (0.1–0.3 M) and doping percentage (2–4%...
