Résumé :

Nickel oxide (NiO) thin films were deposited on glass substrates by chemical spray pyrolysis technique. A high quality crystal was obtained after annealing at 500 K. The structural properties of the films have been studied by the X-ray diffraction (XRD). It has been shown that thin films in the NiO crystallized structure is attained after the deposition. Whatever the precursor molarity, the grain size is about 28-62 nm. The crystallites are preferentially oriented in the directions (111) at 0.2M and (200) at 0.3M.
