The combination of near-infrared active ultrathin nanoshells with their isotropic optical properties is of interest for energy-saving applications. For such applications, the morphology must be precisely controlled, since the optical response is sensitive to nanometer-scale variations. To achieve this precision, we use a multi-step, reproducible, colloidal chemical synthesis. It includes the reduction of Tollens\u2019 reactant onto Sn2+-sensitized silica particles, followed by silver-nitrate reduction by formaldehyde and ammonia. The smooth shells are about 10 nm thick, on average, and have different morphologies: continuous, percolated, and patchy, depending on the quantity of the silver nitrate used. The shell-formation mechanism, studied by optical spectroscopy and high-resolution microscopy, seems to consist of two steps: the formation of very thin and flat patches, followed by their guided regrowth around the silica particle, which is favored by a high reaction rate. The optical and thermal properties of the core-shell particles, embedded in a transparent poly(vinylpyrrolidone) film on a glass substrate, were also investigated. We found that the Ag-nanoshell films can convert 30% of the power of incident near-infrared light into heat, making them very suitable in window glazing for radiative screening from solar light.<\/jats:p>","DOI":"10.3390\/nano13030614","type":"journal-article","created":{"date-parts":[[2023,2,6]],"date-time":"2023-02-06T04:25:28Z","timestamp":1675657528000},"page":"614","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":8,"title":["Silver Nanoshells with Optimized Infrared Optical Response: Synthesis for Thin-Shell Formation, and Optical\/Thermal Properties after Embedding in Polymeric Films"],"prefix":"10.3390","volume":"13","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-3024-0649","authenticated-orcid":false,"given":"Laurent","family":"Lermusiaux","sequence":"first","affiliation":[{"name":"University Bordeaux, CNRS, Bordeaux INP, ICMCB, UMR 5026, 33600 Pessac, France"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-9166-6662","authenticated-orcid":false,"given":"Lucien","family":"Roach","sequence":"additional","affiliation":[{"name":"University Bordeaux, CNRS, Bordeaux INP, ICMCB, UMR 5026, 33600 Pessac, France"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Moncef","family":"Lehtihet","sequence":"additional","affiliation":[{"name":"University Bordeaux, CNRS, Solvay, LOF, UMR 5258, 33608 Pessac, France"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Marie","family":"Plissonneau","sequence":"additional","affiliation":[{"name":"Solvay R&I, 52 rue de la Haie Coq, 93306 Aubervilliers, France"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Laure","family":"Bertry","sequence":"additional","affiliation":[{"name":"Solvay R&I, 52 rue de la Haie Coq, 93306 Aubervilliers, France"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Val\u00e9rie","family":"Buissette","sequence":"additional","affiliation":[{"name":"Solvay R&I, 52 rue de la Haie Coq, 93306 Aubervilliers, France"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Thierry","family":"Le Mercier","sequence":"additional","affiliation":[{"name":"Solvay R&I, 52 rue de la Haie Coq, 93306 Aubervilliers, France"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-0675-5987","authenticated-orcid":false,"given":"Etienne","family":"Duguet","sequence":"additional","affiliation":[{"name":"University Bordeaux, CNRS, Bordeaux INP, ICMCB, UMR 5026, 33600 Pessac, France"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Glenna L.","family":"Drisko","sequence":"additional","affiliation":[{"name":"University Bordeaux, CNRS, Bordeaux INP, ICMCB, UMR 5026, 33600 Pessac, France"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-7902-2442","authenticated-orcid":false,"given":"Jacques","family":"Leng","sequence":"additional","affiliation":[{"name":"University Bordeaux, CNRS, Solvay, LOF, UMR 5258, 33608 Pessac, France"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Mona","family":"Tr\u00e9guer-Delapierre","sequence":"additional","affiliation":[{"name":"University Bordeaux, CNRS, Bordeaux INP, ICMCB, UMR 5026, 33600 Pessac, France"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2023,2,3]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"28","DOI":"10.1016\/j.cis.2011.11.002","article-title":"Silica\u2013metal core\u2013shell nanostructures","volume":"170","author":"Jankiewicz","year":"2012","journal-title":"Adv.
