Morphological and optical study of spray deposited europium chalcogenide thin films

Abstract

Europium chalcogenide (EuS) thin films have been deposited on non-conductive glass substrates in aqueous solution by spray pyrolysis technique at different substrate temperatures. The films synthesized were studied by XRD, SEM, EDAX and UV-Visible spectrometry. The effect of substrate temperature on morphological and optical properties has been investigated. The XRD studies reveal that the material formed on glass substrates is europium sulphide and of polycrystalline in nature. The grain size for the deposited material is about 171 nm. The SEM studies show that total substrate surface is covered by the film with small grains.
