As the \u03b3-ray irradiation increased from 1 h to 3 h with the dose rate of 1190 Gy\/h, the morphology of the Au NPs and the SPR spectrum were found to change. The average diameter of Au NPs increased with the aspect ratio from 1 to 2, and the nano-particles became grown to the clusters. The SPR band wavelength shifted towards a longer wavelength with the increase of total dose of \u03b3-ray irradiation regardless of the corresponding refractive indices. The SPR sensitivities (wavelength\/refractive index unit, nm\/RIU) also increased from 407 nm\/RIU to 3553 nm\/RIU, 1483 nm\/RIU, and 2335 nm\/RIU after the \u03b3-ray irradiation at a total dose of 1190 Gy, 2380 Gy, and 3570 Gy, respectively.<\/jats:p>","DOI":"10.3390\/s19071666","type":"journal-article","created":{"date-parts":[[2019,4,8]],"date-time":"2019-04-08T11:54:52Z","timestamp":1554724492000},"page":"1666","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":5,"title":["Effect of Gamma-Ray Irradiation on the Growth of Au Nano-Particles Embedded in the Germano-Silicate Glass Cladding of the Silica Glass Fiber and its Surface Plasmon Resonance Response"],"prefix":"10.3390","volume":"19","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-4731-0271","authenticated-orcid":false,"given":"Seongmin","family":"Ju","sequence":"first","affiliation":[{"name":"School of Electrical Engineering and Computer Science, Gwangju Institute of Science and Technology, Gwangju 61005, Korea"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-8145-9697","authenticated-orcid":false,"given":"Won-Taek","family":"Han","sequence":"additional","affiliation":[{"name":"School of Electrical Engineering and Computer Science, Gwangju Institute of Science and Technology, Gwangju 61005, Korea"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2019,4,8]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"3","DOI":"10.1016\/S0925-4005(98)00321-9","article-title":"Surface plasmon resonance sensors: Review","volume":"54","author":"Homola","year":"1999","journal-title":"Sens.
