通常情况描述英文此系企业食品为PEG包塑上切换nm顆粒状,食品组合成为NaYREF4 (RE:Yb, Er, Tm, Gd, Mn, Lu),激发起主激出现发亮谱为975 nm。敏化阴阳铝铝离子为Yb3+,激发阴阳铝铝离子为Er3+或Tm3+。能通过自动调节各阴阳铝铝离子掺入浓硫酸浓度,企业食品在目标主激出现发亮谱的出现发亮已获取简化。从表面包塑的PEG使nm顆粒状具备保持良好的亲水性树脂,能会直接散落在水媒介中。企业食品颗粒直径均一,出现发亮量子的工作效率,光平衡性好。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
