ABSTRACT:
This paper reports the optical properties of prepared samarium oxide Sm2O3 thin films nanoparticles using RF sputtering technique. X-ray diffraction is
used to examine and characterize the prepared films. Optical measurements are
carried out by employing U-V-Visible spectroscopy to study optoelectronic properties
ofSm2O3 thin films. These films
are highly transparent in the visible range. The average value of the optical
gap belonging to the thin films deposited under different pressure of the gas
is 4.33 eV. The refractive index (n) behaves as normal dispersion and decreases
with increasing the pressure of the gas. The dispersion energy and single
oscillator energy increase with increasing the pressure of the gas whereas the
optical conductivity decreases with increasing the power on Sb target.
