Abstract
Photodetector devices were created using plasmonic gold nanorods (AuNRs) and cuprous oxide (Cu2O) semiconductor nanoparticles (NPs) in a core-shell design. The study evaluated the functionality and performance of Cu2O NP-based photodiode devices and explored the influence of Au NRs and surface plasmon resonance (SPR) on device response. Both Cu2O NP devices and core-shell AuNR@Cu2O NPs showed efficient photon absorption across a broad visible and near-infrared spectrum, with quick light/dark transitions. The devices exhibited electro-optical response on conductive substrates, demonstrating responsivity between 300-1800 nm wavelengths. These photoconductor-type devices alter electrical resistance when exposed to light under low bias voltage, displaying diverse photodetector responses.
期刊介绍：
The Journal of Alloys and Compounds is intended to serve as an international medium for the publication of work on solid materials comprising compounds as well as alloys. Its great strength lies in the diversity of discipline which it encompasses, drawing together results from materials science, solid-state chemistry and physics.
