EXPLICIT APPLICATION OF SWANEPOEL’S METHOD FOR THE ANALYSIS OF Sb2O3 FILMS

Swanepoel’s method can be applied successfully for the determination of essential optical parameters for films exhibiting interference pattern-type of optical transmission spectra, such those made of antimony trioxide deposited on glass. Refractive index dispersion, absorption spectrum, the real and the imaginary parts of the dielectric constant and the optical conductivity are some of the important features that can be determined by using this valuable method. Also, calculation of films’ thicknesses can be inferred by using Swanepoel’s method. Still, care has to be taken concerning the estimation of film’s thickness from pairs of transmission maxima and/or minima, since important variations may occurs from several computations based on the same spectrum. This article makes a detailed presentation of the application of the mentioned method for the determination of some of the optical features of vacuum-deposited Sb2O3 films.
