LiYbF4:Yb, Er nanoparticles have been successfully synthesized by thermal decomposition of multiple trifluoroacetic acid salts. The SEM and TEM results show the size of the LiYF4:Yb, Er nanoparticles is about 100 nm in diagonal line, and the morphology of the LiYF4:Yb, Er nanoparticles is highly uniform with octahedral structure. Under the excitation of 980 nm, the LiYF4:Yb, Er nanoparticles have higher upconversion luminescence efficiency compared with that of NaYF4:Yb, Er. The results indicate that the as-prepared LiYbF4:Yb, Er nanoparticles may have potential applications in bio-probes and displays.
通过多种三氟乙酸盐的热分解成功合成了LiYbF4:Yb, Er纳米颗粒。扫描电子显微镜(SEM)和透射电子显微镜(TEM)结果表明,LiYF4:Yb, Er纳米颗粒的对角线尺寸约为100纳米,且LiYF4:Yb, Er纳米颗粒的形态高度均匀,具有八面体结构。在980纳米的激发下,LiYF4:Yb, Er纳米颗粒比NaYF4:Yb, Er具有更高的上转换发光效率。结果表明,所制备的LiYbF4:Yb, Er纳米颗粒可能在生物探针和显示器方面具有潜在应用。
