title: A facile synthesis of small-sized and monodisperse hexagonal NaYF4:Yb3+,Er3+ nanocrystals.
abstract: Small-sized (~11.86 nm) and monodisperse hexagonal NaYF4:Yb(3+),Er(3+) upconversion (UC) nanocrystals have been successfully synthesized by simultaneously controlling the nucleation and growth process with a relatively high oleic acid to precursor ratio.
