Title: Synthesis of Sn-doped ZnO nanorods and their photocatalytic properties

Abstract

Graphical abstract: Sn-doped ZnO nanorods have been fabricated by a hydrothermal route. Photocatalytic activity of the Sn-doped ZnO samples increases gradually with an increase of the Sn content. Highlights: {yields} Sn-doped ZnO nanorods were fabricated by a hydrothermal route. {yields} Solid-state NMR result confirms Sn{sup 4+} was incorporated into the lattice of ZnO. {yields} The visible luminescence intensity increased with increase in Sn concentration. {yields} Photocatalytic activity of Sn-doped ZnO increases with increasing Sn content. -- Abstract: Sn-doped ZnO nanorods were fabricated by a hydrothermal route, and characterized by X-ray diffraction, field emission scanning electron microscope, UV-vis spectroscopy, Raman spectra, solid-state nuclear magnetic resonance (NMR) spectra, and room temperature photoluminescence spectroscopy. Solid-state NMR result confirms that Sn{sup 4+} was successfully incorporated into the crystal lattice of ZnO. Room temperature photoluminescence showed that all the as-synthesized products exhibited a weak UV emission (380 nm) and a strong visible emission (540 nm), but the intensities of the latter emission increased with increase in Sn concentration. The improvement of visible emission at 540 nm in the Sn-doped ZnO samples was suggested to be a result of the lattice defects increased by doping of Sn in zinc oxide.
