摘要
利用静电纺丝技术和热处理技术制备了半导体材料纳米纤维,并对其形貌和物理性能进行了研究。结果表明,基于二氧化钛纳米棒的器件在弯曲状态下表现出了比较高的灵敏度和稳定性(如图1所示);在光电性能方面,在不同光强照射时其响应快,灵敏度高,并表现出极好的循环特性和可逆特性,说明二氧化钛纳米棒在柔性光电检测器件方面有着一定的应用潜能。通过低压近场静电纺丝技术与直写打印技术相结合,成功制备了有机P(VDF-Tr FE)纳米纤维与无机(氧化锌、氧化铟)纳米纤维的各种阵列结构,并初步研究了一些相关的光学性质。讨论了氧化锌在不同波长与不同光强度下的光响应情况,为进一步研究纳米线根数对光响应的影响提供了基础。
Semiconductor nanofibers were prepared by electrospunning and followed calcination. The morphologies and physical properties of the nanofibers were characterized. The results showed: the device under bending showed a fast and stable resistance(Fig.1). Photoelectric properties were studied by irradiation and the device exhibited fast response, high sensitivity and good stability under bending, which demonstrated the device could be used as the flexible devices and photodetector devices. Through combining low-voltage near-field electrospinning with direct printing technology, we have prepared various highly aligned nanostructures, such as P(VDF-Tr FE) nanofibers, Zn O nanofibers and In_2O_3 nanofibers. Further more, we also made a preliminary investigation about the photoresponse under the different wavelengths and ultraviolet light intensities for single Zn O nanowire, which provided the basis researches for the further study.
