采用简单的方法在低温水溶液中合成了水溶性镧系元素掺杂的LaF3纳米晶体。纳米晶体的形状接近球形，平均尺寸低于30 nm。它们由结晶良好的六方相组成。水溶液中的发光量子效率约为16%。合成了掺杂不同稀土离子（Eu3+、Ce3+、Tb3+ 和 Nd3+）的 LaF3 纳米晶体，在可见光（VIS）和近红外（NIR）光谱区表现出强发光。
Water-soluble lanthanide-doped LaF3 nanocrystals were synthesized using a simple method carried out in aqueous solution at low temperature. The nanocrystals have a nearly spherical shape and an average size of below 30 nm. They consisted of well crystallized hexagonal phases. The luminescence quantum efficiency was about 16% in aqueous solution. LaF3 nanocrystals doped with different lanthanide ions (Eu3+, Ce3+, Tb3+, and Nd3+) were synthesized, which showed strong luminescence in the visible (VIS) and near-infrared (NIR) spectral regions.
