Layered hexagonal 2H WS2 nanoparticles with preferred c-axis orientation for visible light photodetection

Tungsten disulfide (WS 2 ) nanoparticles were synthesized via a hydrothermal route and characterized to establish the correlation between their structural characteristics and visible-light photodetection performance. X-ray diffraction confirmed a highly crystalline hexagonal 2H-W...
