Volatile organic compound optical fiber sensors: a review
(MDPI, 2006)
Artículo / Artikulua,
Volatile organic compound (VOC) detection is a topic of growing interest with applications in diverse fields, ranging from environmental uses to the food or chemical industries. Optical fiber VOC sensors offering new and ...
Development of an in-fiber nanocavity towards detection of volatile organic gases
(MDPI, 2006)
Artículo / Artikulua,
A fiber optic sensor for Volatile Organic Compounds (VOCs) detection has been developed and characterized for some organic gasses. The sensor is based on a novel vapochromic material, which is able to change its optical ...
Pyridine vapors detection by an optical fibre sensor
(MDPI, 2008)
Artículo / Artikulua,
An optical fibre sensor has been implemented towards pyridine vapors detection; to achieve this, a novel vapochromic material has been used, which, in solid state, suffers a change in colour from blue to pink-white in ...
Sensitivity improvement of a humidity sensor based on silica nanospheres on a long-period fiber grating
(MDPI, 2009)
Artículo / Artikulua,
This work addresses a new configuration that improves the sensitivity of a humidity sensor based on a long-period fiber grating coated with a SiO(2)-nanospheres film. An intermediate higher refractive index overlay, ...
Application of gold complexes in the development of sensors for volatile organic compounds
(World Gold Council, 2007)
Artículo / Artikulua,
Two different kinds of sensors have been developed by using the same kind of vapochromic complexes. The vapochromic materials [Au2Ag2(C6F5)(4)L-2](n) have different colours depending on the ligand L. These materials change, ...
Study and optimization of self-assembled polymeric multilayer structures with neutral red for pH sensing applications
(Hindawi / Wiley, 2008)
info:eu-repo/semantics/article,
The characterization of nanostructured thin films is critical in the design and fabrication of optical sensors. Particularly, this work is a detailed study of the properties of layer-by-layer electrostatic self-assembled ...
Photonic crystal fiber temperature sensor based on quantum dot nanocoatings
(Hindawi / Wiley, 2009)
info:eu-repo/semantics/article,
Quantum dot nanocoatings have been deposited by means of the Layer-by-Layer technique on the inner holes of Photonic Crystal Fibers (PCFs) for the fabrication of temperature sensors. The optical properties of these sensors ...
Optimization of sensitivity in long period fiber gratings with overlay deposition
(Optical Society of America, 2005)
info:eu-repo/semantics/article,
The deposition of an overlay of higher refractive index than the
cladding in a Long Period Fiber Grating (LPFG) permits to improve the
sensitivity to ambient refractive index changes in a great manner. When the
overlay is ...
Analysis of one-dimensional photonic band gap structures with a liquid crystal defect towards development of fiber-optic tunable wavelength filters
(Optical Society of America, 2003)
info:eu-repo/semantics/article,
A theoretical analysis of a fiber optical photonic band gap based
tunable wavelength filter is presented. The design presented here is based on
the quarter wave reflector with a liquid crystal defect layer in the middle ...
Nanofilms on a hollow core fiber
(SPIE, 2006)
info:eu-repo/semantics/article,
We experimentally study the behavior of one multimode fiber–hollow core fiber–multimode fiber structure when nanofilms are deposited on it with the aim of developing practical evanescent field-based devices, such as sensors, ...
