Lattice doped Zn-SnO2 nanospheres: A systematic exploration of dopant ion effects on structural, optical, and enhanced gas sensing properties

- A simple, novel and surfactant free hydrothermal route to prepare SnO2 nanospheres.
- A systematic investigation of growth mechanism with the assist of time dependent HR-TEM images.
- Incorporation of Zn ions into SnO2 lattices clearly elucidated with XRD and XPS spectrums.
- Three fold time increased response in Zn-SnO2 nanospheres when compared to undoped SnO2.
