Résumé : 

This work is a comparative study between the effect of H2O and methanol solvents onmicrostructure, optical and morphological properties of CuO films. CuO films were depositedby the spray pyrolysis method on low price glass at 480°C. Copper nitrate trihydrate has beenused as a precursor of cupric oxide dissolved in different solvents (H2O, methanol) withconcentration 0.1M. CuO thin films were characterized by using X-ray diffraction (XRD),scanning electron microscopy (SEM) coupled with (EDX) and spectrophotometer UV-Vis.The XRD technique showed two characteristics peak (diffraction plans ) (111), (-111)observed on all the elaborated samples that confirms the presence of the CuOmonocrystalline phase. The morphological of surface samples analyzed using the scanningelectron microscope (SEM) indicates the uniformity of the CuO thin films with a periodicstack atoms having crystallographic planes of minimum surface energy density. the CuO thinfilms (methanol) are more porous than CuO thin films (H2O).
