Abstract
A method for manufacturing an ion sensor, especially a pH measurement sensor, based on optical fibre, including the following steps: cleaving the optical fibre, with free hydroxyl groups appearing on the cleavage surface, grafting a layer of trifunctional silane directly on free hydroxyl groups having appeared accordingly on the cleavage surface of the optical fibre, without a prior external activation step, grafting a layer of difunctional silane on the cleavage surface of the optical fibre, and grafting a fluorescent dye.
