Recently, colloidal quantum dots (CQDs) have attracted much interest because of the ease of controlling the dot size and low production cost. In this paper, a high-performance ZnO\/PbS heterojunction photodetector was fabricated by spin-coating PbS CQDs onto the surface of a hydrothermally grown vertical array of ZnO nanowires (NWs) on an indium tin oxide (ITO) substrate. Under 940 nm near-infrared light illumination, the device demonstrated a responsivity and detectivity of ~3.9 \u00d7 104 A\/W and ~9.4 \u00d7 1013 Jones, respectively. The excellent performances and low cost of this nanocomposite-based photodetector show that it has the potential for widespread applications ranging from medical diagnosis to environmental monitoring.<\/jats:p>","DOI":"10.3390\/s23042254","type":"journal-article","created":{"date-parts":[[2023,2,17]],"date-time":"2023-02-17T01:32:56Z","timestamp":1676597576000},"page":"2254","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":9,"title":["High-Performance Near-Infrared Photodetector Based on PbS Colloidal Quantum Dots\/ZnO-Nanowires Hybrid Nanostructures"],"prefix":"10.3390","volume":"23","author":[{"given":"Hefu","family":"Zhong","sequence":"first","affiliation":[{"name":"School of Materials and Energy, Yunnan University, Kunming 650500, China"},{"name":"Kunming Institute of Physics, Kunming 650223, China"},{"name":"Yunnan Key Laboratory of Advanced Photoelectric Materials and Devices, Kunming 650223, China"}]},{"given":"Libin","family":"Tang","sequence":"additional","affiliation":[{"name":"School of Materials and Energy, Yunnan University, Kunming 650500, China"},{"name":"Kunming Institute of Physics, Kunming 650223, China"},{"name":"Yunnan Key Laboratory of Advanced Photoelectric Materials and Devices, Kunming 650223, China"}]},{"given":"Pin","family":"Tian","sequence":"additional","affiliation":[{"name":"Kunming Institute of Physics, Kunming 650223, China"},{"name":"Yunnan Key Laboratory of Advanced Photoelectric Materials and Devices, Kunming 650223, China"}]},{"given":"Lijing","family":"Yu","sequence":"additional","affiliation":[{"name":"Kunming Institute of Physics, Kunming 650223, China"},{"name":"Yunnan Key Laboratory of Advanced Photoelectric Materials and Devices, Kunming 650223, China"}]},{"given":"Wenbin","family":"Zuo","sequence":"additional","affiliation":[{"name":"Kunming Institute of Physics, Kunming 650223, China"},{"name":"Yunnan Key Laboratory of Advanced Photoelectric Materials and Devices, Kunming 650223, China"}]},{"given":"Kar Seng","family":"Teng","sequence":"additional","affiliation":[{"name":"Department of Electronic and Electrical Engineering, Swansea University, Bay Campus, Fabian Way, Swansea SA1 8EN, UK"}]}],"member":"1968","published-online":{"date-parts":[[2023,2,17]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"333","DOI":"10.1016\/S1350-4495(01)00092-5","article-title":"Infrared sensors for ballistic missile defense","volume":"42","author":"Tidrow","year":"2001","journal-title":"Infrared Phys.
