摘要：

High-density single-crystalline Zn2SnO4 nanowires have been successfully synthesized via a simple chemical vapor deposition method by heating a mixture of metal Zn and Sn powders. These straight nanowires with an average diameter of 100-50 nm exhibit rather smooth surface, which is different from the nanowires fabricated by other experiment methods. The growth mechanism of these nanowires is a typical vapor-liquid-solid (VLS) process. In addition, photoluminescence (PL) spectrum of the nanowires was measured, showing strong orange and red emission bands centered at 606.8 and 630.1 nm, respectively, which is rarely observed before. It is maybe ascribed to new luminescence centres caused by the bulk defects related to inverse spinels structure of the Zn2SnO4 nanowires. (C) 2009 Elsevier B.V. All rights reserved.
