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.

Keywords:  band gap; EuS;spray pyrolysis; thin films; XRD.
