Hollow Octahedral Zn2SnO4(ZTO) hierarchical structures were hydrothermally synthesized starting from Zn(Ac)2, SnCl4 and L-lysine in NaOH solution at 200 °C. The XRD result indicates a face-centered cubic phase for the as-prepared octahedral ZTO product with lattice constant a of 0.865 0 nm. Field-emission scanning electron and transmission electron microscopy results reveal that the octahedra are indeed hollow with an edge size of 1∼2 μm and assembled by nanosheets(d: 200∼400 nm) on the surface and edge. Results also demonstrate that the adding amount of NaOH and L-lysine has an immense function in the morphology control of octahedral ZTO hierarchical structures. The photoluminescences of the as-fabricated ZTO products with different shapes all display a broad strong green emission band at 550∼600 nm but different in intensity at room temperature.
