The successive ionic layer adsorption and reaction (SILAR) method was used for the deposition of dysprosium sulfide (Dy2S3) thin films on stainless steel (SS) substrate. The X-ray diffraction (XRD) study showed orthorhombic crystal structure of Dy2S3. Scanning electron microscopic study revealed microstructure with randomly distributed spherical nanostructured particles. The films exhibited hydrophilic nature with a contact angle of 50° and a specific surface area of 48 m2g-1. The electrochemical properties of Dy2S3 films in 1 M Na2SO4 electrolyte displayed maximum specific capacitance (Cs) of 273 F g−1 at a scan rate of 5 mVs−1.
