Monodispersed CaF(2):Yb(3+)/Er(3+) nanocrystals have been prepared via a facile wet chemical technology. The upconversion luminescence properties of CaF(2):Yb(3+)/Er(3+) nanocrystals were compared with those of NaYF(4):Yb(3+)/Er(3+) nanocrystals with different phases and particle sizes. The results indicated that CaF(2) is a promising host material for producing desirable upconversion luminescence.
通过一种简便的湿化学技术制备了单分散的CaF₂:Yb³⁺/Er³⁺纳米晶体。将CaF₂:Yb³⁺/Er³⁺纳米晶体的上转换发光特性与不同相和粒径的NaYF₄:Yb³⁺/Er³⁺纳米晶体进行了比较。结果表明，CaF₂是一种用于产生理想上转换发光的有前景的基质材料。
