The Effect of Substrate Temperature on the Optical Constant of CuO Thin Films Prepared by Chemical Spray Pyrolysis Technique.

Abstract

Copper oxide thin film have been deposited on the glass substrates at
different temperatures of (623,673,723,773)K by Spray Pyrolysis method,
the effect of substrate temperature on the optical constant of films have
been studied. The absorbance and transmittance spectra have been recorded
by (UV-VIS) spectrophotometer in the wavelength range of (380-900)nm.
It was found that the absorbance, increases while transmittance decreased
by increasing substrate temperature, The optical constants such as
(reflectance, extinction coefficient, refractive index, real and imaginary part
of dielectric constant and optical conductivity) have been analyzed.
