| Abstract: The fluorine scandium nanocrystals (NCs) with different morphologies, phase structures and properties of upconversion luminescence (UCL) were synthesized through changing the reaction conditions such as the composition, the amount of the surfactant or the reaction time. The change of the ratio of surfactant oleic acid (OA)/oleylamine (OM) made the crystal structure change from cubic ScF3:Yb, Er to orthorhombic KSc2F7:Yb, Er NCs with the enhanced UCL, while the morphology transformed from small to bulky. The UCL of the KSc2F7 NCs could be tuned from blue through white, and then to dominant purple emissions by changing doped element under the excitation of 980 nm laser. |
