The influence of annealing temperature on the slip plane activity and optical properties of nanostructured ZnO films
The zinc oxide films were prepared by the sol-gel method on the ordinary glass substrates. The activity of slip systems were evaluated by X-ray diffraction line broadening analysis using convolution multiple whole profile (CMWP) fitting procedures. It was found that in all temperatures the < a > type dislocations is dominating and its fraction increases with the rise of annealing temperature in the range of 350-600 degrees C. The investigation on the optical properties of films showed that the optical band gap energy increases linearly with the annealing temperature and crystallite size but decreases with the lattice strain.
