| 摘 要： | 用化学气相沉积法在管式炉中制备了SnO2掺Ag纳米线.纳米线直径约50 nm,长几十微米.通过XRD、TEM和Raman谱仪等测量确定SnO2掺Ag纳米线为金红石型结构,XPS谱表明样品中含有Sn、O和Ag元素,Ag的浓度约为1.8 at.%,室温PL谱显示样品在626nm处有很强的红光发射峰.

| Abstract: | Ag doped SnO_2 nanowires were synthesised by chemical vapor deposition(CVD) method in a typical horizontal tube furnace.The diameter and length of these nanowires were about 50 nanometers and tens of micrometers,respectively.XRD,TEM and Raman spectroscopy results showed that these nanowires were rutile SnO_2 sturcture.XPS spectrum revealed that these nanowires consisted of Sn,O and Ag elements,and the concentrate of Ag was about 1.8 at.%.PL spectra showed that the products exhibited a strong red-light emiss... |
