The present work displays a thorough study of the optical spectroscopy of multilevel RE-doped tin oxide nanocrystals. Our study provides the structural grounds about the behavior of the RE emission under site-selective excitation as well as the capability of the host to hold the RE ions at the nanocrystal lattice sites and, as a consequence, the possibility to reach the RE excited states by direct host excitation.
