Paper Abstract
The fiber optic pH sensor described is based on a colorimetric pH indicator and a pH insensitive luminescent compound co-immobilized in a hydrophilic polymer. The absorption spectra of the pH indicator and the luminescent compound overlap. Consequently, the competitive absorption between the pH indicator and the luminescent compound results in modulation of the sensor emission intensity as a function of pH in the measurement media. The feasibility of this pH measurement technique is demonstrated with on-line testing of fiber optic sensors.
