合成了单分散的稀土氟化物纳米晶，并将其作为构建块来制备双模发光胶体球，该胶体球由两个不同的单元组成，一个在紫外光激发下提供下转换发光，另一个在980 nm激光激发下提供上转换发光，在多路复用和高灵敏生物检测中具有潜在的应用前景。
Monodisperse rare-earth fluoride nanocrystals are synthesized and used as building blocks to fabricate dual-mode luminescent colloidal spheres, which are composed of two distinct units, one offering down-converting luminescence under UV excitation and the other providing up-converting luminescent emission when excited with a 980 nm laser, and have potential applications in multiplexed and highly sensitive bioassays.
