Influence of different post-tretments on the physical properties of sprayed zinc oxide thin films

Résumé

Polycrystalline ZnO thin films have been prepared on glass substrates by spray pyrolysis technique. The deposition temperature was varied between 350°C and 570°C. The effects due to post-thermal annealing on the structure and optical properties of thin films have been studied depending on the annealing temperature in the range of 200 ÷ 550°C. The crystal structure and surface characteristics were investigated by mean of X-ray diffraction (XRD) and scanning electron microscopy (SEM). The optical properties were studied by optical transmission spectrometry using a UV-VIS spectrophotometer. The optical measurements reveal that thin films have a maximum transmittance of about 86% and a direct band gap of 2.29 eV. XRD and SEM both indicate that increasing the annealing temperature results in an increase of the c-axis-oriented columns on the glass substrates.
