Nanoparticle Size Control in Microemulsion Synthesis
Quasi-monodisperse
populations of (H<sub>3</sub>O)ÂY<sub>3</sub>F<sub>10</sub>·<i>x</i>H<sub>2</sub>O nanocrystals
of varying size are prepared in Igepal-stabilized microemulsions.
Correlations between microemulsion composition, micelle hydrodynamic
radius, and final nanoparticle size are established and shed light
on the mechanism of particle size control. Under the conditions considered
here, size control appears to be primarily governed by the number
of micelles and the quantities of precursor ions. More specifically,
the number of NPs formed can be successfully correlated with the number
of micelles present and final NP size is, in turn, determined by the
number of nuclei and the total amount of material available for nanocrystal
formation. This insight into nanoparticle formation facilitates the
selection of appropriate synthetic conditions for the preparation
of populations of a targeted size
