Abstract:
This
research investigates the effect of deposition time and temperature on the
optical and structural properties of cadmium oxide (CdO) thin films prepared by
the chemical bath deposition (CBD) method. (CdO) thin films were deposited on
glass substrates at different temperatures and deposition times. The optical
and structural properties of the prepared films were studied using optical
spectroscopy and X-ray diffraction (XRD). The results showed a clear variation
in the values of transmittance, absorbance, and energy bandgap of the prepared
films.
Which
aims to:
1)
Understanding the crystal structure (structural properties):
To
determine the arrangement of atoms within the material (whether it is
crystalline or not), the grain size, growth orientation, and the presence of
defects or impurities.
2)
Determining the quality of the thin film:
By
studying uniformity, thickness, and structural regularity, since these factors
directly affect the material’s performance.
3)
Analyzing the interaction with light (optical properties):
Such
as transmittance, absorbance, and reflectance, which are important for
understanding how the material behaves when exposed to optical radiation.
4)
Calculating the energy band gap:
One
of the most important properties that determines the suitability of the
material for electronic and optical applications such as solar cells or
sensors.
5)
Relating preparation conditions to final properties:
Such
as temperature and deposition time, to understand how they influence the
structure and optical properties, and thus improve the preparation method.
6)
Guiding practical applications:
Such
as using thin films in solar cells, smart windows, or optical device.
