Tungsten Disulfide (WS2) Pristine Flakes in Solution, 100 ml

Tungsten Disulfide (WS2) Pristine Flakes in Solution, 100 ML WS2 Pristine Flakes are nanoscale crystals dispersed in ethanol/water solution. If separated from solution, nano-WS2 forms bright-green crystals, that look different from silver-grey crystals of bulk WS2. Properties: Lateral Size: 50-150 nm Thickness: 1-4 monolayers Purity in dry phase: >99% Solution Concentration: 26 mg/L Solution is stable under ambient conditions This solution can be easily deposited onto a substrate or surface of your choice to form a thin film coating.   SEM image of thin-film WS2 after the solution was used to coat SiO2   UV-Visible Absorption Spectrum Bulk WS2 forms dark gray hexagonal crystals with a layered structure. They are not chemically active and can only be dissolved by a mixture of nitric and hydrofluoric acids. Each W(IV) center of WS2 is occupying a trigonal prismatic coordination sphere, which is bound to six sulfide ligands. The sulfur centre is connected to three tungsten centres,
