The letter reports synthesis of samarium telluride (Sm2Te3) thin films through a one-step chemical route. The formation of Sm2Te3 is confirmed by X-ray diffraction and X-ray photoelectron spectroscopy studies. The surface morphological study is carried out using field emission scanning electron microscopy and contact angle measurement techniques. The film shows barley-like microstructure with an average length of barley of about 5 tim and diameter of about 300 nm. The Sm2Te3 film surface exhibits lyophilic nature with contact angle of 21.3 for propylene carbonate electrolyte. Cyclic voltammetry results revealed specific capacitance of 207 F g(-1) with power density of 14.18 kW kg(-1) in LiC104-propylene carbonate electrolyte. (C) 2015 Elsevier B.V. All rights reserved.
