Abstract	De nombreux domaines, tels que le biomedical, la micro-fluidique ou l'optique quantique, sont demandeurs de nanoparticules presentant des proprietes optiques specifiques. L'ablation laser en liquide, PLAL (Pulsed Laser Ablation induced in Liquid) est une methode de synthese permettant d'elaborer rapidement des nanoparticules dans une large gamme de materiaux, et donc de tester la conservation ou la modification des proprietes optiques originales identifiees dans certains materiaux lorsque l'on passe aux tailles nanometriques (scintillation, thermoluminescence, photo-stimulation, haut rendement de luminescence...). Dans ce travail de these la synthese, la caracterisation optique et structurale de nanoparticules dopees a ete developpe. Differents types de materiaux ont ete testes dont l'oxyde de gadolinium dope, l'yttrium aluminium garnet (YAG), l'alumine etc. Cela a permis de montrer la faisabilite et la potentialite de cette technique d'elaboration sur differents materiaux. Par ailleurs un outil de diagnostic du plasma par spectroscopie optique resolue en temps a ete mis en place afin de comprendre les processus des croissances des particules formees.
