STUDY OF THE OPTICAL PROPERTIES OF THIN FILMS.

Abstract

Thin film of tin sulfide (SnS) is deposited on to glass substrates using chemical spry pyorlysis thin films. The solution prepared by 0.2 M and used temperature at 350 and the distance between the nozzle and glasses substrate 35cm . obtained The optical constant such as (refractive index n and Extinction coefficient κ) of the deposition films were obtained from the analysis of the experimental recorded transmittance spectral data. The optical band gap of SnS films calculate from . photon energy curve. The energy gap was found to be in the range 1.4eV to 1.85 eV.
