一样表述此题材成品为PEG覆盖上转化成納米级小粒,的原材料組成为NaYREF4 (RE:Yb, Er, Tm, Gd, Mn, Lu),增加主光谱为975 nm。敏化阳化合物为Yb3+,成功激活阳化合物为Er3+或Tm3+。凭借调低各阳化合物添加浓硫酸浓度,成品在独特主光谱的带光已有调优。表明覆盖的PEG使納米级小粒极具优秀的亲水性聚氨酯,都可以随时疏散在水导电介质中。成品粒级均一,带光量子热高效率,光不稳性好。This series of products contains PEG coated NaYREF4 (RE:Yb, Er, Tm, Gd, Mn, Lu) UCNs with optimal excitation wavelength at 975 nm. The sensitizer is Yb3+, and the activator is Er3+ or Tm3+. The doping concentrations are optimized, leading to strong upconverted emissions at specific wavelengths.The nanoparticles are highly hydrophilic due to the PEG coating.The UCNs are of high quantum efficiency and very photostable
