Silver nanoprisms are grown with a photoreduction method and account for the SERS, which have better electromagnetic enhancement than spherical silver nanoparticles at 785 nm. Due to the antiresonant reflecting guidance mechanism, the excited laser and SERS signal are effectively guided in such a fully filled hollow-core photonic crystal fiber SERS probe and complicated selective filling with target sample is avoided. Rhodamine 6G molecules are used as probe molecules and the simplified hollow-core photonic crystal fiber SERS probe is test. Detection of low concentration Rhodamine 6G down to 10\u22128 M is achieved with a short integration time of 300 ms.<\/jats:p>","DOI":"10.3390\/s18061726","type":"journal-article","created":{"date-parts":[[2018,5,29]],"date-time":"2018-05-29T02:58:18Z","timestamp":1527562698000},"page":"1726","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":11,"title":["A Simplified Hollow-Core Photonic Crystal Fiber SERS Probe with a Fully Filled Photoreduction Silver Nanoprism"],"prefix":"10.3390","volume":"18","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-0019-3813","authenticated-orcid":false,"given":"Youfu","family":"Geng","sequence":"first","affiliation":[{"name":"Collage of Physics and Energy, Shenzhen Key Lab. of Sensor Technol., Shenzhen University, Shenzhen 518060, China"}]},{"given":"Yiwen","family":"Xu","sequence":"additional","affiliation":[{"name":"Collage of Physics and Energy, Shenzhen Key Lab. of Sensor Technol., Shenzhen University, Shenzhen 518060, China"}]},{"given":"Xiaoling","family":"Tan","sequence":"additional","affiliation":[{"name":"The Electronic Communication Department, Shenzhen Institute of Information Technology, Shenzhen 518172, China"}]},{"given":"Lina","family":"Wang","sequence":"additional","affiliation":[{"name":"Collage of Physics and Energy, Shenzhen Key Lab. of Sensor Technol., Shenzhen University, Shenzhen 518060, China"}]},{"given":"Xuejin","family":"Li","sequence":"additional","affiliation":[{"name":"Collage of Physics and Energy, Shenzhen Key Lab. of Sensor Technol., Shenzhen University, Shenzhen 518060, China"},{"name":"School of Science and Engineering, The Chinese University of Hong Kong (Shenzhen), Shenzhen 518172, China"}]},{"given":"Yu","family":"Du","sequence":"additional","affiliation":[{"name":"Collage of Physics and Energy, Shenzhen Key Lab. of Sensor Technol., Shenzhen University, Shenzhen 518060, China"}]},{"given":"Xueming","family":"Hong","sequence":"additional","affiliation":[{"name":"Collage of Physics and Energy, Shenzhen Key Lab. of Sensor Technol., Shenzhen University, Shenzhen 518060, China"}]}],"member":"1968","published-online":{"date-parts":[[2018,5,28]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"777","DOI":"10.1109\/LPT.2014.2306134","article-title":"Gold Nanoparticles-Modified Tapered Fiber Nanoprobe for Remote SERS Detection","volume":"26","author":"Chen","year":"2014","journal-title":"IEEE Photonics Technol.
