N2 - Electrospun-based ZnO granular nanofibers (GNFs), with the granular feature which are able to modulate energy band along axises of the fibers, are regarded as great candidates to develop the UV photodetectors with high performance. However, when exposed to air, the oxygen absorption and desorption make the devices suffer from sluggish response. Here, via an easy and cost effective method of polydimethylsiloxane (PDMS) coating, the photo-response speed of electrospun-based ZnO GNFs photodetectors was enhanced by more than 104 times. The giant enhancement was attributed to both gas isolation and surface electron state passivation. The results exhibited an effective method to enhance response speed of electrospun-based GNFs photodetectors.
