Abstract
In this work, 0-5wt.% copper doped zinc
oxide thin films were deposited by spray
pyrolysis technique (homemade) on 375°C
heated glass. Zinc acetate (Zn (CH3COO)2,
2H2O) and copper chloride (CuCl2,7H2O)
were used as sources precursor of ZnO and
Cu doping, respectively. Effect of copper
0-5wt.% doping concentration on optical
and structural properties was studied. UV visible transmission techniques, X-ray
diffraction were used respectively to
characterize optical and structural
properties of elaborated thin films. The
average transmittance of all samples was
more than 81% in the visible region and
become more transparent with Cu doping.
Optical gap energy was found to be in
3.25-3.28eV range. X-ray diffraction
studies show nanocrystalline thin films
with a hexagonal wurtzite structure
exhibiting a strong (002) preferred
orientation. Particles size ranges in 23-
29nm for 0-5wt.% Cu doped ZnO thin
films
