Phetsahai, P. Eiamchai, K. Thamaphat, P. Limsuwan","doi":"10.3116/16091833/24/4/04046/2023","DOIUrl":"https://doi.org/10.3116/16091833/24/4/04046/2023","url":null,"abstract":". We synthesize and separate triangular silver nanoplates (TSNPs) from a mixture of colloidal silver nanoparticles of different shapes and sizes, aiming at fabrication of substrates for a surface-enhanced Raman scattering (SERS). The TSNPs are successfully synthesized via a photochemical process involving Ag nanoseeds. This is confirmed by the UV-visible spectroscopy and transmission electron-microscopy analyses. Centrifugation-based separation techniques are employed to isolate the TSNPs and minimize the other nanoparticle morphologies, thus resulting in a good SERS performance. The separated TSNPs manifest a remarkable sensitivity, with the detection limit amounting to 10 –12 M in the case of Rhodamine 6G molecules. A linear relationship between the Rhodamine 6G concentration and the Raman-peak intensity demonstrates a great potential of our SERS technique. Hence, our study combines a successful synthesis and separation of the TSNPs with demonstration of their efficient SERS performance. The latter offers new possibilities for the ultrasensitive trace-level detection of substances. These findings contribute to the development of reliable SERS measurements and the advance in the field of nanomaterial-based sensing techniques.","PeriodicalId":23397,"journal":{"name":"Ukrainian Journal of Physical Optics","volume":null,"pages":null},"PeriodicalIF":3.9,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"69617842","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"物理与天体物理","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
