High performance UV light photodetectors and ethanol gas sensor based on graphene oxide doped SnO2 nanotubes |
| 초록 |
The effect of graphene oxide (GO) on the ethanol sensing and photodetector performance of SnO2 nanotubes (NTs) were studied. Pristine SnO2 NTs were produced via electrospinning method, whereas GO-SnO2 NTs were produced by dipping SnO2 NTs in a GO solution with a suitable annealing. The pristine and GO-SnO2 NTs showed higher response, towards ethanol gas compared to other gases with an optimum working temperature of 300°C. Integration of GO on the surface of SnO2 NTs can be a suitable method to enhance the sensing performance. Then, pure and doped SnO2 nanotubes based photodetectors were constructed, GO-SnO2 NTs exhibits good quantum efficiency and short response time compare with pristine SnO2 nanotubes. The high performance of the doped SnO2 nanotubes can be attributed to the perfect crystallinity and the special GO-embedded structure. 2019년 한국교통대의 지원을 받아 수행하였음. |
