Tungsten Selenide Nanoparticles

Introduction:

Tungsten selenide nanoparticle is a compound composed of tungsten (W) and selenium (Se), forming a binary transition metal dichalcogenide (TMD) structure. This material is part of a family of two-dimensional materials known for their unique properties that can be fine-tuned at the nanoscale. Tungsten selenide nanoparticles, specifically in their nanoparticle or nanopowder form, exhibit exceptional optical, electrical, and mechanical properties due to their quantum behavior and 2D layer structure.

WSe₂ is often synthesized using various methods, including chemical vapor deposition (CVD), hydrothermal methods, and exfoliation techniques, which result in high-quality nanoparticles with a controlled size, morphology, and surface area.
