dc.description.abstract | Uniform perovskite core-shell nanocubes NaMn1-xMgxF3@NaMgF3 and NaMn1-xMgxF3:Yb3+@NaMgF3:Yb3+ have been successfully synthesized via a facile one-pot co-precipitation method at room temperature. The core-shell structures were carefully characterized by powder X-ray diffraction, transmission electron microscopy, scanning transmission electron microscopy and energy-dispersive X-ray elemental mapping. It was found that the formation mechanisms of the novel core-shell structures consisting of aggregation of precursor molecules/ions, multiple nucleation, surface re-crystallization and further phase transformation. In addition, the DFT calculations further showed that Mn2+ ions tend to aggregate in NaMgF3:Mn2+, and which may be one of important intrinsic factors for formation the unique NaMn1-xMgxF3@NaMgF3 structure in this case. Besides, the unique core-shell structures NaMn1-xMgxF3:Yb3+@NaMgF3:Yb3+ can obviously enhance near-infrared upconversion luminescence of Mn2+, that may find high potential in multiple high-resolution imaging applications. | |
