• , including light-emitting diodes, laser diodes, and photodetectors for the ultraviolet (UV) spectral range [1][2]. ZnO nanostructures are particularly interesting as they bear superior properties compared to the bulk crystal. UV-light detection is one of the major applications of ZnO, and various UV

• photodetectors based on ZnO films or nanocrystals have been reported. It has been demonstrated that ZnO nanowires have high internal photoconduction gain and much stronger responsivity under UV-light illumination compared to the bulk film [3]. The UV photoresponse mechanism of ZnO nanowires is dominated by the

• block the UV light. Moreover, carbon-based polymers undergo oxidation with ageing, and the degradation could be expedited by the absorption of UV light. In this paper, we report results of experiments on UV photodetectors based on a thin sheet of ZnO nanowires embedded in polydimethylsiloxane (PDMS
