Europium sulphide (EuS) thin films are successfully deposited on non-conductive bare silicon glass substrates by spray pyrolysis technique at various precursor volume proportions of europium chloride and thaiocatamide. The films were studied by XRD, SEM and UV-Visible spectrometry. The effect of varying precursor volume proportions was studied on morphological and optical properties. The XRD conformed polycrystalline nature. Study enlights the foremost impact of precursor volume proportions on morphological and optical properties.
