“…Of course the drawing of the preform induced a very little aggregation of the particles due to the thermal energy supplied during the high temperature drawing process. Since the residence time of the part of the glass preform into the fiber during the drawing process was short within several seconds, no significant diffusion and migration of the particles were expected …”

Specialty optical fibers incorporated with CdSe and CdMnTe quantum dots are fabricated using the modified chemical vapor deposition and high temperature fiber drawing process. Temperature dependence of Faraday rotation angle (FRA) is investigated under magnetic field of 0.126 Tesla (T) upon temperature change from 25 to 120 °C. The FRAs of the CdSe and CdMnTe doped fibers are found to increase linearly with magnetic field and no appreciable change in the FRA of the CdSe doped fiber with the increase of temperature is found regardless of the magnetic field as compared to the CdMnTe doped fiber. Average temperature dependence of the FRA are 16.40 × 10−4 and −104.90 × 10−4 degree °C−1 at 0.126 T for the CdSe and CdMnTe doped fibers and the resultant Verdet constants are estimated to be 3.75 ± 0.04 and 3.50 ± 0.12 rad T−1 m−1, respectively.

“…Thus gold particles with the larger size may be responsible to the SPR absorption. Forthermore, the coupling effect originated from the dipole-dipole interactions of the aggregateed Au particles would also lead to a broad absorption band [49]. For g-C 3 N 4 , a strong absorption around 400 nm was observed, confirming the ability of absorbing sunlight with a wider wavelength.…”

“…The fiber-optic SPR sensor is an alternative to overcome the disadvantages of previous conventional prism based SPR sensor because of its attractive advantages of simple and flexible design, compactness, and remote sensing capability for all-optical applications. Recently, we have reported the fiber-optic refractive index sensor using the novel optical fiber incorporated with Au NPs in the cladding [42,57]. In this paper, hence, we report the effect of γ-ray irradiation on the SPR sensing capability by inducing the morphological change in Au NPs embedded in the fiber.…”

“…Furthermore, various post-processing techniques of the irradiation by the pulsed laser, the charged ion, and the γ-ray have been investigated to control NPs with desired size and shape [33][34][35][36][37][38][39][40]. Our group has reported a heat treatment method to control the size of NPs in glass fiber [41][42]. Among such post irradiation processing techniques, the high energy irradiation was proven to control effectively the size, shape, and spacing of the NPs by creating ion tracks resulting from Coulomb explosion and/or thermal spikes accompanying the excitations [43][44][45][46].…”

The effect of γ-ray irradiation on surface plasmon resonance (SPR) sensing capability of refractive index (n = 1.418–1.448) of the silica glass optical fiber comprised of germano-silicate glass cladding embedded with Au nano-particles (NPs) was investigated. As the γ-ray irradiation increased from 1 hour to 3 hours with the dose rate of 1,190 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 peak wavelength shifted towards longer wavelength with the increase of total dose of γ-ray irradiation regardless of the corresponding refractive indices. The SPR sensitivities (wavelength/refractive index unit, nm/RIU) also increased from 407 nm/RIU to 3,553 nm/RIU, 1,483 nm/RIU, and 2,335 nm/RIU after the γ-ray irradiation at the total dose of 1,190 Gy, 2,380 Gy, and 3,570 Gy, respectively.
