New sensor systems using surface plasmon resonance (SPR) have been developed for measuring the refractive index (RI) of an analyte. 1,2 The systems use an optical phenomenon in which incident light excites a charge-density wave at the interface between a metal and a dielectric. 1,2 An SPR sensor allows the realization of quick determination of the RI of a sample with high accuracy. However, the usual SPR sensor systems utilize bulk optical configurations that are limited by the use of a coupling prism. Furthermore, since the SPR system requires a spectrometer or a rotation stage, the resulting systems are relatively large and expensive, are inapplicable for remote sensing applications. 3 Optical fiber sensors based on the SPR phenomenon have been developed. These systems replace a coupling prism with an optical fiber, and the SPR phenomenon is applicable to analyses of liquid or gas samples. The systems have a sensing element of a deposited metal film on the core of an optical fiber and must scan the wavelength 3,4 or change the angle of incident light. [5][6][7][8][9][10][11][12][13][14][15] Another type of the sensor based on SPR in a thin deposited metal film on the core of an optical fiber implanted in a silica block and polished has been reported. [16][17][18][19][20][21][22][23] A gold island SPR sensor has also been investigated. [24][25][26][27][28][29] Most theoretical analyses for the optical fiber sensors using SPR are based on the traditional Kretschmann configuration and the response curves have been calculated. 3,6,12,14,[16][17][18][19][20][21][22][23][30][31][32][33][34] However, these analyses are made for the sensors in a restricted range of the refractivity (less than 1.45 RI units). Thus, a theoretical investigation of the response of the gold-deposited optical fiber sensor over a wider range of refractivity is necessary to understand the mechanism of the response.An optical fiber sensor system based on SPR without scanning the wavelength or changing the angle of incident light is desired for remote sensing, continuous analysis, and in situ monitoring using a small and inexpensive sensing element. We have already developed a small and simple gold-deposited optical fiber sensor system without scanning the wavelength or changing the angle of incident light. [35][36][37][38][39][40] The sensing element has a thin (30 -60 nm) gold film deposited all around the bare core of an optical fiber and a sample solution flows around it. When light with an intensity distribution is introduced into the optical fiber of the sensor with a focusing lens, the SPR occurs at the interface between the gold film and the sample solution. A part of the incident light disappears by the SPR and the intensity of the transmitted light varies depending on the refractivity of the sample solution. [35][36][37][38][39][40] We have performed the analyses of various alcohol solutions [35][36][37][38][39][40] and some esters in ethanol 36 and have demonstrated the usefulness of this sensor system. Theoretical analyses for the ...

“…(15) Since then, numerous SPR sensing structures for chemical and biochemical sensing have been generating continuously growing attention from the scientific community. (16)(17)(18) For the past few years, the use of SPR as a heavy ion metal sensor had been widely studied. (19)(20)(21)(22)(23)(24)(25)(26)(27) However, SPR has not been applied to the sensitive and selective detection of Zn 2+ in aqueous solutions.…”

Tetrabutyl thiuram disulfide (TBTDS) immobilized in chitosan thin film has been studied as a sensor element for zinc ion, Zn 2+ , using surface plasmon resonance (SPR). The TBTDS-immobilized chitosan thin film, which acts as an active layer, was coated on a gold film by spin coating. Zn 2+ can be detected by measuring the SPR signal when TBTDS-immobilized chitosan thin film contacts with Zn 2+ in solution. The sensor produced a linear response for Zn 2+ ranging from 0.1 to 1 ppm with a sensitivity of 0.0317° ppm −1 . Using immobilized TBTDS as an active layer, the Zn 2+ can also be selectively detected when present in mixtures of heavy metal ions.

“…[1][2][3] Gold (Au) and silver (Ag) are the most widely used metals for the sensor elements and the sensor properties depend on the dielectric constant (εr + εii) of the deposited metal. [4][5][6][7] Sensor systems which scan the wavelength [8][9][10][11][12][13][14][15][16][17] or change the angle of incident light [18][19][20][21][22][23][24][25][26][27][28] have been proposed. Though other types of sensor system based on SPR do not require a change in the incident angle, they do need many optical parts for their construction.…”

The performance of a simple gold (Au)-deposited optical fiber sensor system based on surface plasmon resonance (SPR) is presented. Our sensor system comprises a light-emitting diode (LED) and a photodiode (PD) as the light source and the detector, respectively. The response curves and sensor properties of the Au-deposited optical fiber with a Au film thickness of 45 nm obtained by using three LEDs with 563, 660, and 940 nm emissions were investigated. The sensor properties depend strongly on the wavelength of the incident light and can be controlled by changing the LED emission wavelength. The response curves of the sensor obtained at the three wavelengths and calculated using SPR theoretical equations were compared with those obtained by experimentation. Our sensor system represents a new SPR-based refractometer with performance almost equal to that of an Abbe refractometer. To demonstrate its usefulness, ethanol concentrations in various spirits were measured and the results compared with those as labeled.
