Abstract

Optical fiber carbon dioxide gas sensors are reported. The sensors utilize pH sensitive indicator dyes, which change color, when exposed to varied concentrations of CO₂. Sensors were made by deposition of silica sol solution on the Plastic Clad Silica fiber side surface. The possibility of preparing the sensors by deposition of active layer on the surface of etched fibers has also been demonstrated. Dependence between the fiber diameter and the sensitivity of the sensor has been presented. Morphology of the active layer has been investigated by the analysis of SEM images.
