Effect of different S/In ratio of In2S3 films prepared by chemical spray pyrolysis method
Abstract : In2S3 thin films were prepared using chemical spray pyrolysis technique. An aqueous solution of InCl3 and CS(NH2)2 was sprayed on to glass substrates and kept at 300 °C, using air as a carrier gas. Stoichiometry of the films was varied by adjusting the molarity of the spray solution. Structure and properties of films with different S/In ratios have been investigated. Raman spectroscopy present bands at 302 and 329 cm-1 indicating the presence of the β-phase in all the films. Optical transmittance of films is over 80% in the visible region and its energy band gap decreases from 2.7 to 2.67 ev. PL emission in the wavelength range 300-800 nm was recorded.
