Synthesis a sol-gel for Chemical fiber sensor

Plastic Optical Fiber pH Sensor Using a Sol-Gel Sensing Matrix

Sol-gel synthesis of ordered mesoporous alumina.

Well-ordered mesoporous alumina materials with high surface area and a narrow pore size distribution were synthesized using a sol-gel based self assembly technique.

Sol-gel-based, planar waveguide sensor for water vapor.

A water vapor sensor based on a combination of sol-gel processing and planar optical waveguide technologies has been developed. The indicator erythrosin B was entrapped in a thin sol-gel film (thickness ∼100 nm) prepared from methyltriethoxysilane, dimethyldiethoxysilane, and tetraethoxysilane. This dye exhibits an increase in absorbance in the presence of liquid or gaseous water. The sol-gel l...

Synthesis and Characterization of Sb doping on thick film SnO2 Gas Sensor by Sol-Gel Method

Tin oxide (SnO2) thin films are widely used by solgel method. One of the most important factors that influence the sensitivities of sensing material is its structural properties especially surface morphology. In this work, we present preparation and characterization of undoped and antimony-doped tin oxide (Sb: SnO2) thin film nanostructures for gas sensing applications. The films were character...

A fiber optic sensor for measuring glucose in aqueous solutions

In this paper, the set-up of a multi-mode fiber optic sensor for measuring glucose in aqueous solutions is investigated and evaluated. The basis of this sensor is based on the Fresnel Reflection. In this setup, a helium-neon laser is used as a light source, a fiber optic probe, photocell as detector and a digital multimeter. The statistical analysis of the recorded data shows a highly linear be...
