| 摘 要： | 以ZnO、SnO2和活性炭的混合物为原料,通过碳热还原热蒸发法无催化剂成功制备出Zn2SnO4纳米材料.借助X射线衍射仪(XRD)、拉曼光谱和扫描电子显微镜(SEM)对样品物相和形貌进行了表征,结果显示样品为面心立方结构的Zn2SnO4纳米链状棒,同时含有少量的ZnO物相.利用X射线光电子能谱(XPS)对Zn2SnO4样品表面各元素的化学状态及相互作用方式进行了测试,结果表明:样品中Zn和Sn分别是以+2价和+4价氧化态形式存在,其中Zn2p3/2电子有两个结合能,分别来自ZnO和Zn2SnO4,Zn2SnO4中Sn4+占据不同的格点位置.室温下光致发光谱(PL)结果显示,样品在紫外区域(320-450nm)和可见区域存在很强的发光带,其中紫外区域的宽发光带,经过高斯拟合可分为358和385nm两个发光峰,与同条件下制备得到的纯ZnO纳米材料发光谱比较,确认358nm发光峰是来自于Zn2SnO4的近带边复合发光.

| Abstract: | We synthesized Zn2SnO4 nanomaterials by the carbon-thermal evaporation method with Zn,SnO2 and C powder mixture,without using a catalyst,to investigate the controllable synthesis of Zn2SnO4 nanomaterials and to study their optical properties in the ultraviolet region.The structure,and morphology of the as-grown products were characterized by X-ray diffraction(XRD),Raman spectroscopy,and scanning electron microscopy(SEM).X-ray photoelectron spectroscopy(XPS) was also used to study the type of binding of the ... |
