Fiber-optic sensor for butylamine

Abstract

Abstract. Fiber-optic chemical sensor for butylamine was realized. The sensor includes a thin layer nanostructure on the end of optical fiber with a diameter of 600 µm. It consists of luminescent silica nanoparticles modified with pyrylocyanine dye, silver nanoparticles and photonic-crystal film. The sensitivity of the sensor is increased tenfold due to an additional covering of the film with photonic crystal as a porous mirror and the injection of silver nanoparticles with a diameter of 5-7 nm.

Optical Sensors Based on Opal Film and Silica Nanoparticles Modified with a Functional Dye

“…These sensors utilize the optical properties of chemicals or products of chemicals or biological reactions to assess contaminants to monitor process quality, provide compliance monitoring and evaluate real-time insitu contaminant levels in uncontrolled and remediated hazardous waste sites. The coating of the thin-film nanostructures based on silica nanoparticles on the surface of optical fiber allows significantly extend the scope of fiber-optic sensors (Boldov et al, 2011). We have realized for the first time a fiber-optic chemical sensor for butylamine.…”
