Rare-earth-doped magnetic-optic bifunctional alkaline-earth metal fluoride nanocrystals have been successfully synthesized via a facile microwave-assisted process. The as-prepared nanocrystals were monodisperse and could form stable colloidal solutions in polar solvents, such as water and ethanol. They show bright-green fluorescence emisson. Furthermore, Gd(3+)-doped ones exhibit paramagnetic behavior at room temperature and superparamagnetic behavior at 2 K.
通过简便的微波辅助法成功合成了掺稀土的磁光双功能堿土金属氟化物纳米晶。所制备的纳米晶单分散性好，在极性溶剂如水中和乙醇中可形成稳定的胶体溶液。它们表现出亮绿色的荧光发射。此外，掺钆的纳米晶在室温下表现出顺磁性，在 2 K 下表现出超顺磁性。
