Crystalline low agglomerated tungsten diselenide (WSe2) nanoparticles were successfully produced by the aerosol synthesis method. The particle size and morphology were changed by process parameters. The products were characterized by X-ray diffraction and high-resolution transmission electron microscopy. The WSe2 nanoparticle morphology varies from a spherical shape to flake-like, layered structures. Usually, as-prepared particles consist of 5–7 single layers of WSe2. These as-synthesized WSe2 nanoparticles were used as anodes to assemble lithium-ion batteries. A high reversible capacity and very stable cycle performance can be obtained, implying that these WSe2 nanostructures could provide new types of electrode materials for rechargeable Li-ion batteries.

. These thin films exhibited the minimum band gap energy. Moreover, WSe 2 nanoparticles have been synthesized by chemical vapor condensation method for Li-ion battery anodes [ 28 ]. In this study, WO 3 thin films were spin prepared by spin coating method at different deposition cycles and their sensor responses towards various concentrations of NO 2 gas were investigated. The structural, morphological, optical, and electrical properties of WO 3 films were studied using X-ray diffraction (XRD), scanning electron microscopy (SEM), FT-Raman spectra and electrical
