| 摘 要： | 用简单有效的静电纺丝法制备了Ce掺杂的In2O3纳米纤维材料.采用X射线衍射(XRD)、透射电子显微镜(TEM)、高分辨率透射电子显微镜(HRTEM)和扫描电子显微镜(SEM)对合成样品的晶体结构和形貌进行了表征.结果显示,此纤维材料的平均直径约为90nm,长度达到几十个微米.气敏性能测试结果表明,4%(w)Ce掺杂的In2O3纳米纤维对三乙胺的灵敏度最高,该气敏元件对3μL·L-1三乙胺的灵敏度达到2.6,响应时间为5s,恢复时间约为6s,且具有较好的选择性.

| Abstract: | Ce-doped In2O3 nanofibers were synthesized by a simple and effective electrospinning method. The morphology and crystal structure of the as-prepared samples were characterized by X-ray diffraction (XRD),transmission electron microscopy (TEM), high-resolution transmission electron microscopy (HRTEM), and scanning electron microscopy (SEM). The results revealed that the length of the nanofibers can reach several tens of micrometers and the average diameter was about 90 nm. The sensor fabricated from the 4% (w) Ce-doped In2O3 nanofibers showed the highest sensitivity to triethylamine. The sensitivity reached 2.6 when the sensor was exposed to 3 μL·L-1 triethylamine and the response time and recovery time were about 5 and 6 s, respectively. Moreover, good selectivity was also observed in our investigation. |
