Abstract

L'invention concerne un procédé de fabrication de particules mixtes composées d'un coeur d'oxyde métallique réfractaire, inerte et non ou faiblement luminescent, recouvert par une couche d'oxyde métallique luminescente nanostructurée contenant au moins 1% en poids d'ions lanthanide dont la taille des cristallites est inférieure à 100 nm, et de préférence inférieure à 50nm, comprenant notamment une étape essentielle de lyophilisation, ainsi que les nanoparticules obtenues selon un tel procédé.
