Recently, UV-visible-NIR nanowire (NW) photodetectors are emerging for potential applications, such as optical communications, optical interconnects. However, the enhancement of sensitivity and response time for broad spectral range are still challenging. In this study, we report highly sensitive, fast UV-visible-NIR NW photodetectors based on inorganic-organic hybrid material. Specifically, PbS quantum dot (QD)-poly(3-hexylthiopehene) P3HT hybrid NWs are grown on electrodes by the meniscus-guided method. The hybrid NW photodetectors show high ON/OFF ratio for UV and visible lights and fast response time for UV light. The high performances are attributed to charge transfer between PbS QD and P3HT. We also demonstrate an stretchable UV-visible-NIR photodetectors array of PbS QD-P3HT nanoarchs bridged electrode embedded in PDMS. The stretchable photodetectors array shows an identical photoresponse under extreme stretching conditions and repeated stretching. |
