Abstract: | Large-scale Zn2SnO4 hexangular microprisms were successfully synthesized through a simple thermal evaporation method by heating metal Zn and Sn powders under varying temperatures. The synthesized microprisms are single-crystalline, tens of micrometers in length. And their surfaces have many nano-scale skewed steps along the axial direction. Structurally, we supposed that the hexangular prism could be described as a row of inlaid octahedron of Zn2SnO4 crystals. A broad asymmetrical emission band was observed in the PL spectrum of these Zn2SnO4 microprisms, which was discussed in detail in the paper. |
