Abstract
Our work consists in depositing the copper oxide Fe doped CuO films
by spray obtained from the solution of copper chloride CuCl2 and
FeCl2 with a percentage of 2, 4; 6 and 8%, on glass substrates at a
temperature of 3500c. The thin films obtained are characterized by X ray diffraction, visible UV spectroscopy and the four-point
technique.With X-ray diffraction, high peak intensity is obtained for
the preferential orientations of (002) and (111), this intensity increases
as the doping rate increases and gives us a more crystalline structure
for a doping rate of 8%, also a grain size were estimated. The
transmission of our films varies between 55% and 75% with a high
absorption in the visible domain, the resistivity of our films increase
with the increase of doping rate and the gap energy varies between 4.00
and 1.47 eV
