Abstract
This work aims the preparation and of nanomaterials based on oxides and fluorides doped with different rare earth (RE) ions, which act both as optical markers and as energy converters for photosensitization of singlet oxygen molecules in biological systems. Bi-functional core-shell nanocomposites - luminescent and magnetic - based on Fe3O4@ RE2O3, Li(RE)F4 will be prepared aiming evaluati…
