Passivation of lanthanide surface sites in sub-10 nm NaYF(4):Eu(3+) nanocrystals

We examined in detail the optical properties of NaYF(4):Eu(3+) nanocrystals of ~9 nm in diameter. For such small nanocrystals roughly 17 % of Y(3+) ions occupy surface sites and can be efficiently substituted by optically active Eu(3+) ions. In order to determine the influence of surface Eu(3+) on t...
