“…To fabricate the POF SERS sensor, we used the etching method [42] to prepare the POF tip with a diameter of 2 μm-3 μm. Then several drops of gold nanorods colloids were placed directly on the POF tip and dried naturally.…”

An overview of recent researches of surface plasmon resonance (SPR) sensing technology in Laboratory of Science and Technology of Micro-Nano Optics (LMNO), University of Science and Technology of China, is presented. Some novel SPR sensors, such as sensors based on metallic grating, metal-insulator-metal (MIM) nanoring and optical fiber, are designed or fabricated and tested. The sensor based on localized surface plasmon resonance (LSPR) of metallic nanoparticles is also be summarized. Because of the coupling of propagating surface plasmons and localized surface plasmons, the localized electromagnetic field is extremely enhanced, which is applied to surface-enhanced Raman scattering (SERS) and fluorenscence enhancement. Future prospects of SPR and/or LSPR sensing developments and applications are also discussed.

“…Then in the first sample, labeled as LM-1 in table 1, the outer jacket is simply stripped off in an approximately 2 cm length and the fiber tip polished. The second sample, labeled as LM-2 in table 1, keeps approximately the same length of exposed fiber, but the fiber diameter is homogeneously reduced by chemical etching with pure acetone to a diameter of 880 µm [16][17][18]. With this procedure, cladding and part of the core of the fiber distal end is removed.…”

Highly Sensitive Extrinsic X-Ray Polymer Optical Fiber Sensors Based on Fiber Tip Modification

Abstract-An extrinsic X-ray fiber sensor with improved sensitivity is presented. The developed device is based on an inorganic scintillator (Terbium doped Gadolinium Oxysulfide) attached to a polymer fiber tip. Sensitivity improvement has been accomplished by modifying the fiber tip in two ways, either by thermomechanical tapering of chemical etching. Thus, the useful surface in contact with the scintillator increases, and so the fluorescence light gathering capability. All the fabricated devices have been tested under X-ray irradiation from a Linac at a dose rate of 300 monitor units/min, with a readout every 100 ms. The obtained results shown a signal improvement of up to 43 times when compared with previous reported proposals using inorganic scintillators and polymer fibers. Moreover, the recorded signal under the same measurement conditions can be further improved if the inorganic scintillator is used in powder format instead into an epoxy matrix.

“…The fiber core outer diameter is 980 µm. It has been previously reported that the PMMA optical fiber can be bi-conically tapered at the fiber tip using 60% acetone, 20% MIBK and 20% distilled water (AMD solution) [20]. In our work this method has been modified to carry out etching of core at the centre of fiber.…”

ABSTRACT-Detection of fuel adulteration in real time is the most important need of the world as it generates the hazardous effects on the environment, living and nonliving things. Various automotive users and fuel providers may mix kerosene in petrol and diesel. Adulterated fuel increases air pollution, as well as reduces the performance of vehicle engines. Such a malpractice in fuel is prevailing because vehicles do not have real time adulteration monitoring system. In this study, we propose evanescent wave optical fiber sensor, which is interfaced with peripheral interface controller (PIC) to detect fuel adulteration percentage by means of change in refractive index. A fuel sensor prototype is formulated and tested to detect adulteration percentage in petrol and diesel by kerosene. The sensor is useful as it has simple construction, real time operation, and safety handling with inflammable fuel for in-situ measurements. The sensors have detectable capacity of 5% contaminant in petrol and diesel using evanescent wave absorption technique. Other traditional techniques are able to detect presence of about more than 10 % of fuel adulteration only in the laboratory. PIC is used with a fuel sensor for incorporating an automation and sophistication in automotive display, so that it is more useful to layman.
