ABSTRACT = {In this work, CuO thin films about the synthesis of the thin films are prepared on glass 
substrate using spray pyrolysis technique at room temperature different annealing times in 
temperature 450 
0
C.In order to study the effect of annealing times onthe structural, optical 
and electrical properties.XRD analysis has shown that films with a polycrystalline 
structurehave a(Monoclinic) structure.In addition, the crystallite phase CuO increases with 
increasing of annealing temperature.Moreover, with a preferred orientation along (002) 
peak.The optical properties confirmed that the elaborated films have a transmittance of 
70%. We have found that the band gap energy (Eg) is a decreasing function with respect to 
the annealing temperature time. In addition, the electrical resistivity varies from 18.97 to 
4.58 KOhm.cm for the films grown at different annealing times. },
