AB  - In this study, a Dielectric Barrier Discharge
DBD plasma system used to affect the pure thin Cadmium
Oxide (CdO) films. This system produces non-thermal
plasma at atmospheric pressure using frequency (500
kHz) and a voltage between (100-1500 kV). Thin films of
cadmium oxide have prepared on clean glass stands at
350	°C by thermal chemical spraying and cadmium acetate
(Cd(CH<sub>3</sub>COO)2.2H<sub>2</sub>O) was used as a source material of
Cd with concentration about (0.1 M) dissolving in 50 mL
re-distilled water. The Ultraviolet (UV) spectrum of films
using optical absorption calculations which were taken in
spectral area between (350-1100 nm), the transmittance
and reflectance for films in the Ultraviolet-Visible area
(UV-VIS) and effect of exposure to plasma on
absorbance, transmittance, absorption coefficient, energy
gap, extinction coefficient, refractive index, real and
imaginary dielectric constant and optical conductivity
have studied in this study. The results showed that both of
the transmittance and the energy gap decreases when
exposure time for plasma increases while absorption and
absorption coefficient, refraction, extinction coefficient,
real and imaginary dielectric constant and optical
conductivity increase when exposure time for plasma
increases.
