Effect of precursor medium on morphological and optical characterization of spray deposited EuO thin films

Europium chalcogenide (EuO) thin films have been deposited by spray pyrolysis technique on non-conductive bare soda lime glass substrates in aqueous and non-aqueous precursor mediums. The films synthesized are characterised by XRD, SEM, EDAX and UV-Visible spectrometry. The effect of precursor medium on morphological and optical properties has been investigated. The XRD studies reveal that, the films are polycrystalline in nature and the deposited material was europium oxide. It was found that, morphological and optical properties are strongly related to the precursor medium. The SEM analysis conformed the formation of small spherical and square shaped grains on overall substrate.
