摘要
A scheme of a fiber chemical sensor of amine-type compounds has been implemented. The sensor includes a film nanostructure deposited on the end face of an optical fiber 600 mu m in diameter. The film consists of luminescent silica nanoparticles modified by functional pyrylocyanine dye, silver nanoparticles, and a photonic crystal opal film. An additional coating of the sensor film from above by a porous selective mirror, such as a photonic crystal, and introduction of silver nanoparticles 5-7 nm in diameter into it make it possible to increase the sensor sensitivity by an order of magnitude.
