Hydrophilic Ce, Tb doped BaYF(5) nanocrystals with uniform size were synthesized by a microwave-assisted route. The synthesized nanocrystals can be well dispersed in hydrophilic solutions (DMSO, DMF, EG, H(2)O). This synthesis procedure represents a less time consuming method, with high product yield and without using any assistant or/and template reagents, which may be expected to be a general method for rapid synthesis of other hydrophilic RE doped fluoride fluorescent nanocrystals. The Ce(3+), Tb(3+) codoped BaYF(5) nanocrystals show bright green fluorescence emission. The Ce(3+) acts as an effective energy transfer medium and the emission at the high (5)D(3) energy level of Tb is enhanced in this host material.
通过微波辅助法合成了具有均匀尺寸的亲水性 Ce、Tb 掺杂 BaYF(5)纳米晶体。所合成的纳米晶体可以很好地分散在亲水性溶液（DMSO、DMF、EG、H(2)O）中。该合成方法耗时更短，产率更高，无需使用任何辅助剂或/和模板试剂，有望成为快速合成其他亲水性 RE 掺杂氟化物荧光纳米晶体的通用方法。Ce(3+)、Tb(3+)共掺杂 BaYF(5)纳米晶体呈现明亮的绿色荧光发射。在这种基质材料中，Ce(3+) 充当有效的能量转移介质，并且 Tb 的高（5）D(3)能级的发射得到增强。
