Abstract
Tin sulphide thin films have been synthesized in aqueous media in the presence of triethanolamine using electrodeposition method. The effect of deposition potential, triethanolamine concentration and deposition time towards the properties of tin sulfide films was studied. The presence of triethanolamine showed improvement in reproducibility, adherence and crystallinity of the films. The X-ray diffraction studies indicated formation of polycrystalline compounds. The properties of the films varied with the variation in the deposition parameters. The highest photoresponse was obtained for the film deposited at −0.80 V in the presence of 0.06 M triethanolamine. Films deposited at longer deposition time showed higher photoresponse. The absorbance study revealed that the bandgap energy was about 1.20 eV with indirect transition.
