Abstract
A series of Yb/Tm co-doped NaGdF4nanoparticles without or with a thin surface protection layer provide direct evidence of a surface quenching effect on size-dependent upconversion luminescence (see picture). The coating preserves the optical integrity of the nanoparticles (right-hand spectrum) and minimizes emission loss induced by surface quenching. © 2010 Wiley-VCH Verlag GmbH & Co. KGaA.
