Abstract

L'invention vise à produire un émetteur à fluorescence pour la gamme d'ondes de la lumière ultraviolette et visible, qui soit chimiquement stable et non toxique ou faiblement toxique et puisse être mis en suspension dans l'eau. A cet effet, il est prévu d'utiliser des nanoparticules fluorescentes présentant un noyau consistant en une matière de céramique d'oxyde et une enveloppe contenant une matière fluorescente et un polymère ou un copolymère.
