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.

金纳米棒。铜(I)氧化物核壳纳米颗粒,用于全可见到近红外响应光电探测器
利用等离子体金纳米棒(aunr)和氧化亚铜(Cu2O)半导体纳米颗粒(NPs)在核壳设计中创建了光电探测器器件。本研究评估了基于Cu2O np的光电二极管器件的功能和性能,并探讨了Au nmr和表面等离子体共振(SPR)对器件响应的影响。Cu2O NP器件和核壳AuNR@Cu2O NP器件在广泛的可见光和近红外光谱上都表现出高效的光子吸收,具有快速的明暗转换。该器件在导电衬底上表现出电光响应,在300-1800 nm波长之间表现出响应性。这些光导体型器件在低偏置电压下暴露于光下时改变电阻,显示出不同的光电探测器响应。
