Abstract

The preparation of LiNbO :Er /Yb nanocrystals and their up-conversion properties have been studied. It is demonstrated that polyethyleneimine- (PEI) assisted dispersion procedures allow obtaining stable aqueous LiNbO :Er /Yb powder suspensions, with average size particles well below the micron range (100-200 nm) and the isoelectric point of the suspension reaching values well above pH 7. After excitation of Yb ions at a wavelength of 980 nm, the suspensions exhibit efficient, and stable, IRto-visible (green and red) up-conversion properties, easily observed by the naked eye, very similar to those of the starting crystalline bulk material. © 2011 Springer-Verlag. 3 3 3+ 3+ 3+ 3+ 3+
