文摘

Samarium doped-lutetium oxide nanoparticles smaller than 15 nm were obtained by co-precipitation method. The Sm3+ loading was carefully evaluated in order to maximize Sm3+ emission avoiding concentration quenching phenomena. Intense Sm3+ NIR emission was observed. The nanoparticles showed no toxicity at low concentration towards to HECV cells.
