Chemically deposited tin sulphide

SnS thin films were deposited on glass substrates after multi-deposition runs by chemical bath deposition from aqueous solution containing 30 ml triethanolamine (TEA) (C6H15NO3) (50%), 10 ml thioacetamide (CH3CSNH2),8 ml ammonia (NH3) solution and 10 ml of Sn2+(0.1 M). These films were characterised with X-ray diffraction (XRD), with scanning electron microscopy, and with spectro photometric measurements. The obtained thin films exhibit the zinc blend structure, the crystallinity seems to be improved as the film thickness increases and the band gap energy is found to be about 1.76 eV for film prepared after six depositions runs.
