Paper Abstract

Fluorescent chemical sensors have been widely exploited for the detection and quantification of trace explosives. Their performances are mainly dependent on the sensitive material. Fluorescent organic materials are very efficient in terms of sensitivity, selectivity and response time but their degradation is a major drawback. Sol-gel materials offer a much longer life span, especially in the case of inorganic sensitive coatings. The elaboration of sol-gel sensitive films is detailed in this paper. Two examples of sol-gel fluorescent sensitive materials are presented: a hybrid organic-inorganic film and an inorganic material.
