Abstract

Advances in fiber optic sensors and, in particular, the technique of electropolymerization have led to a development which allows for porphyrins, the sensing molecules, to be attached directly onto the tip of an optical fiber. The sensing element as a whole is very robust, since during the process of electropolymerization the molecule forms a matrix on the surface of the fiber-film, thus ensuring no leeching of the film constituents to the surrounding environment. Luminescence lifetime decays were obtained using a novel dedicated instrumentation system. The data was analyzed using high level languages incorporating mathematical modeling capabilities. The results of this work are reported as well as a detailed discussion of the electropolymerization process with respect to the porphyrins.
