Preparation and Studying the Optical Properties of (Sb2o3) Thin Films

Abstract

In this paper I present the preparation of (Sb₂o₃) thin films using thermal evaporation in vacuum, procedure with different thickness  (100 ,150 _,200 ,and 250) nm, by using ( hot plate) from Molybdenum matter at temperature in ( 900⁰c) and the period of time (15mint) ,the prepared in a manner thermal evaporation in a vacuum and precipitated on glass bases, pure Antimony Trioxide (sb₂o₃ ) thin films with various condition have been successfully deposited by (T.E.V) on glass slide substrates. The substrates temperature of about 100^oC and the vacuum of about 10^-6 torr, to investigated oxidation of evaporated, measure spectra for prepared films in arrange of wavelength (250 – 1100 nm). The following optical properties have been calculated: the absorption coefficient, the forbidden (E_g) for direct and indirect transitions "absorbance, refractive index,  extinction coefficient, real and imaginary parts" of the dielectric constant.
