Abstract
A high-performance ZnS-based UV photodetector (PD) with novel nanoparticle-anchored silver nanowires (NP-anchored Ag NWs) networks as enhanced platform is reported. The materials’ d-spacing and crystallite size were calculated using XRD date which are in good agreement with HRTEM results. Benefitting from the plasmonic gap effects in the NP-NW junctions, the fabricated photodetector yields a fast response speed (tr = 0.04 s and td = 0.05 s), decent on/off ratio (482), high responsivity (1.8 × 103 A/W) and excellent detectivity (3.3 × 1013 Jones). The strategy presented in this work may be instructive for designing high-performance optoelectronic devices.
