文摘Lanthanide-doped ultrasmall nanoparticles(NPs)are attractive for diverse applications because of their unique optical properties compared with their bulk materials;their practical use,however,is greatly limited by extremely weak photoluminescence(PL)associated with severe surface quenching.Herein,we demonstrate an effective strategy to activate surface dark emitters of Eu3+in ultrasmall Sc_(2)O_(3).
