P-type Sb doping hierarchical WO3 microspheres for superior close to room temperature ammonia sensor

Nanosheet-assembled microspheres of tungsten oxide doped with antimony were synthesized via hydrothermal method. Sb doping changed the valency of W, promoted a partial crystal phase transition from orthorhombic to hexagonal, and modified the surface morphology. Further, WO3 is an n-type semiconducto...
