Abstract
Zinc oxide thin films were prepared from three different solvents using the sol–gel technique. Zinc acetate was used as the source of Zn, and the solvents ethanol, 2-methoxy ethanol and ethylene glycol were used to prepare the sols. ZnO thin films were deposited on glass microslides by pre-heating dip coated sol layers, following which they were finally annealed at 450 °C for half an hour. The films were characterized using structural, morphological and optical techniques. XRD studies show that the films grown from all the three solvents were single phase, highly oriented (along the c axis) ZnO having the wurzite structure. Optical transmission and photoluminescence spectra confirm the good quality of the ZnO films. SEM and AFM images show that the surfaces of the ZnO films, obtained using the first two (more volatile) solvents, consist of striations or ridges of height around 100–400 nm and are made up of nanoparticles 20–40 nm in size. The surfaces of the films produced from the less volatile third solvent are however smooth and devoid of striations although they are also covered with nanoparticles.
