Optical Fiber Sensor for Detection of Carbon Nanotubes
This work relates the development of an optical fiber (OF) sensor for the detection and quantification of single walled carbon nanotubes in aqueous solutions. The developed OF displays a compact design, it requires less expensive materials and equipment as well as low volume of sample (0.2 mL). This methodology was also validated by the comparison of its analytical performance with that of a st...
متن کاملThin film composite optical waveguides for sensor applications: a review.
We review the design and fabrication of thin-film composite optical waveguides (OWG) with high refractive index for sensor applications. A highly sensitive optical sensor device has been developed on the basis of thin-film, composite OWG. The thin-film OWG was deposited onto the surface of a potassium-ion-exchanged (K(+)) glass OWG by sputtering or spin coating (5-9mm wide, and with tapers at b...
متن کاملAn Optical Fiber Sensor Probe Using a PMMA/CPR Coated Bent Optical Fiber as a Transducer for Monitoring Trace Ammonia
Ammonia sensors have broad spectrum of applications for industrial process control as well as for environmental monitoring. An optical fiber ammonia sensor probe has been developed by using a bent optical fiber having dual poly(methyl methacrylate) (PMMA)/chlorophenol red (CPR) coatings as a transducer. This sensor probe was tested for monitoring trace ammonia in gas samples using air as sample...
متن کاملDynamic Response of Tapered Optical Multimode Fiber Coated with Carbon Nanotubes for Ethanol Sensing Application
Ethanol is a highly combustible chemical universally designed for biomedical applications. In this paper, optical sensing performance of tapered multimode fiber tip coated with carbon nanotube (CNT) thin film towards aqueous ethanol with different concentrations is investigated. The tapered optical multimode fiber tip is coated with CNT using drop-casting technique and is annealed at 70 °C to e...
متن کاملHigh performance dielectric film using SiO2-coated short carbon nanotubes in BaTiO3-polymer composite
Three-phase composite films consisting of BaTiO3/singlewalled carbon nanotube (SWCNT)/polymer were fabricated. The SWCNTs were shortened and coated with SiO2 to minimise the conducting paths of the SWCNTs in the film. The film showed a dielectric constant and dielectric loss of 92 and 0.031, respectively, at a frequency of 1 kHz. The SiO2-coated short SWCNTs can play important roles in enhancin...
