dc.description.abstract | Synthesizing upconversion materials with 3-dimensional structures is of fundamental importance in understanding the relationship between their optical properties and their structures. In this paper, we report a simple but useful synthetic method to produce highly monodisperse 3-dimensional YF3:Yb3+/Er3+ microcrystals showing variable upconversion efficiencies. By tuning the pH, precursor salt, and solvent, the shapes of the YF3:Yb3+/Er3+ crystals could be tuned from hollow hexagon to hollow dumbbell, tetragonal bipyramid, and truncated tetragonal bipyramid structures. The upconversion efficiency showed significant dependence on the structure of YF3:Yb3+/Er3+; hollow structures revealed a large enhancement in the luminescence intensity. The upconversion efficiency of the structures decreased in the order hollow hexagon > hollow dumbbell > tetragonal bipyramid > truncated tetragonal bipyramid. | - |
