The samples have been prepared by varying the Ag/In ratio in solution from 0 % to 4 %. The effect of silver on structural and optical properties of In2S3Ag thin films has been investigated in detail using various characterization tools. XRD patterns confirmed that all the films have a nanocrystalline nature. The Raman spectroscopy showed the main mode at 306 cm-1 and 327 cm-1 indicating the presence of the β-phase in all films. Optical transmittance of spray pyrolyzed films exceeds 80% in the visible region and band gaps are estimated varying from 2.60 eV to 2.73 eV. © 2016 IEEE. %G English %L hal-02434101 %U https://centralesupelec.hal.science/hal-02434101 %~ SUP_LMOPS %~ CENTRALESUPELEC %~ UNIV-LORRAINE %~ LMOPS-RAMAN
