Abstract  

Up-conversion luminescent NaYF4:Yb3+/Er3+ nanomaterials were synthesized using a solvo-thermal method. It was determined that the size, morphology, and luminescence intensity of these nanoparticles can be controlled by varying the concentration of fluoride ions. Low reactant concentrations were found to always result in monodisperse, hexagonal nanocrystals, and to gradually and uniformly decrease the size of the NaYF4 nanocrystals. In contrast, at higher concentrations, the nanocrystals grow to form a mixed phase. Fluoride ion concentrations over a specific range tend to promote the fluorescence emission of the material and may also significantly affect the fluorescent lifetime.
