摘要

该信函介绍了用于宽带光敏应用的CuO， V2O5和V2O5/CuO纳米结构的可扩展合成。采用单一纳米结构材料（CuO, V2O5）和异质结构（V2O5/CuO）制备了三种不同的宽带照明器件并进行了测试。该异质结构器件在360 nm处的响应率和探测率分别为1.23 A/W和0.97\ × 10 ^{11}$ Jones。该异质结构器件的响应率分别是CuO和V2O5的67.3倍和13.8倍。实验结果表明，V2O5/CuO异质结构可用于实时光学传感应用。

High-Performance Broadband Photodetectors With V2O5/CuO Heterojunction

The letter presents the scalable synthesis of CuO, V2O5 and V2O5/CuO nanostructures for broadband photosensing applications. Three different devices using single nanostructured material (CuO, V2O5) and heterostructure (V2O5/CuO) were fabricated and tested for broadband illumination. The heterostructured device demonstrates the responsivity and detectivity of 1.23 A/W and

$0.97\times 10 ^{11}$

Jones at 360 nm respectively. The responsivity of the heterostructured device is 67.3 times and 13.8 times higher than CuO and V2O5 respectively. The demonstrated results indicate that the V2O5/CuO heterostructure could be useful for real time optical sensing applications.

期刊介绍： IEEE Photonics Technology Letters addresses all aspects of the IEEE Photonics Society Constitutional Field of Interest with emphasis on photonic/lightwave components and applications, laser physics and systems and laser/electro-optics technology. Examples of subject areas for the above areas of concentration are integrated optic and optoelectronic devices, high-power laser arrays (e.g. diode, CO2), free electron lasers, solid, state lasers, laser materials'' interactions and femtosecond laser techniques. The letters journal publishes engineering, applied physics and physics oriented papers. Emphasis is on rapid publication of timely manuscripts. A goal is to provide a focal point of quality engineering-oriented papers in the electro-optics field not found in other rapid-publication journals.
