In order to overcome the problem of AgNPs easily oxidizing in the air, this paper synthesizes AgNPs using the improved Tollens method and effectively suppresses the coffee-ring effect by changing the solution evaporation conditions, so that the distribution of AgNPs in the deposition area is relatively uniform. The structure proposed in this paper takes advantage of the flexibility of nanoparticle application. The AgNPs deposited on the dielectric layer can effectively localize energy and regulate the LSPR of the device well. The structure can not only achieve precise regulation of the LSPR resonance peak of AgNPs but also can be used as a SERS substrate.<\/jats:p>","DOI":"10.3390\/s24175778","type":"journal-article","created":{"date-parts":[[2024,9,5]],"date-time":"2024-09-05T08:36:08Z","timestamp":1725525368000},"page":"5778","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":2,"title":["A Surface-Enhanced Raman Scattering Substrate with Tunable Localized Surface Plasmon Resonance Absorption Based on AgNPs"],"prefix":"10.3390","volume":"24","author":[{"ORCID":"https:\/\/orcid.org\/0009-0006-5450-5823","authenticated-orcid":false,"given":"Guanzhou","family":"Lin","sequence":"first","affiliation":[{"name":"National Key Laboratory of Advanced Micro and Nano Manufacture Technology, Beijing 100871, China"},{"name":"School of Integrated Circuits, Peking University, Beijing 100871, China"}]},{"given":"Meizhang","family":"Wu","sequence":"additional","affiliation":[{"name":"School of Instrument Science and Opto-Electronics Engineering, Beijing Information Science and Technology University, Beijing 100096, China"},{"name":"School of Automation, University of Science and Technology Beijing, Beijing 100083, China"}]},{"given":"Rui","family":"Tang","sequence":"additional","affiliation":[{"name":"National Key Laboratory of Advanced Micro and Nano Manufacture Technology, Beijing 100871, China"},{"name":"School of Integrated Circuits, Peking University, Beijing 100871, China"}]},{"given":"Bo","family":"Wu","sequence":"additional","affiliation":[{"name":"National Key Laboratory of Advanced Micro and Nano Manufacture Technology, Beijing 100871, China"},{"name":"School of Integrated Circuits, Peking University, Beijing 100871, China"}]},{"given":"Yang","family":"Wang","sequence":"additional","affiliation":[{"name":"National Key Laboratory of Advanced Micro and Nano Manufacture Technology, Beijing 100871, China"},{"name":"School of Integrated Circuits, Peking University, Beijing 100871, China"}]},{"given":"Jia","family":"Zhu","sequence":"additional","affiliation":[{"name":"School of Electronic Engineering and Computer Science, Peking University, Beijing 100871, China"}]},{"given":"Jinwen","family":"Zhang","sequence":"additional","affiliation":[{"name":"National Key Laboratory of Advanced Micro and Nano Manufacture Technology, Beijing 100871, China"},{"name":"School of Integrated Circuits, Peking University, Beijing 100871, China"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-5506-9257","authenticated-orcid":false,"given":"Wengang","family":"Wu","sequence":"additional","affiliation":[{"name":"National Key Laboratory of Advanced Micro and Nano Manufacture Technology, Beijing 100871, China"},{"name":"School of Integrated Circuits, Peking University, Beijing 100871, China"},{"name":"Frontiers Science Center for Nano-Optoelectronics, Peking University, Beijing 100871, China"}]}],"member":"1968","published-online":{"date-parts":[[2024,9,5]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"83","DOI":"10.1038\/nphoton.2009.282","article-title":"Plasmonics beyond the diffraction limit","volume":"4","author":"Gramotnev","year":"2010","journal-title":"Nat.
