The Effect of Thickness on Some Optical Properties of Sb2S3 Thin Films Prepared by Chemical Bath Deposition

Abstract

Sb2S3 thin films have been prepared by chemical bath deposition on a glas sub Absorbance and transmittance spectra were recorded in the wavelength range (30-900) nm. The effects of thickness on absorption coefficient, reflectance, refractive index, extinction coefficient, real and imaginary parts of dielectric constant were estimated. It was found that the reflectivity, absorption coefficient , extinction coefficient, real part of dielectric constant and refractive index, all these parameters decrease as the thickness increased, while the imaginary part of the dielectric constant increase as the thickness increased.

THE LATEST PROGRESS ON SYNTHESIS AND INVESTIGATION OF Sb2S3-BASED THIN FILMS

“…It found that the reflection coefficient, adsorption coefficient, real part of the dielectric permittivity, and refractive index decrease with increasing film thickness, while the imaginary part of the dielectric permittivity increases. [79].…”
