Description
Summary:2 D materials show fascinating properties for their applications in advanced technology. Tungsten Diselenide (WSe2), a family of transition-metal dichalcogenides, has greatly inspired researchers to take up challenges in energy storage, optoelectronic and electronic applications. We have synthesized WSe2 using hydrothermal technique via the reaction of sodium tungstate and selenium power with the assistance of sodium borohydride, a reducing agent and N, N- dimethylformamide (DMF) and deionized water have been utilized as double solvent. The structural and the surface morphological properties of WSe2 have been studied using X-ray diffraction and Field Emission Scanning Electron Microscope (FESEM) which approve the high crystallinity and reveal the most thermodynamically stable Hexagonal phase of WSe2. The successful synthesis of this new class of 2D material motivated us to perform ion beam bombardment experiments for modifying its properties especially for energy applications.
