此系列产品为氨基功能化上转换纳米颗粒，材料组成为NaYREF4 (RE:Yb, Er, Tm, Gd, Mn, Lu)，最佳激发波长为975 nm。敏化离子为Yb3+，激活离子为Er3+或Tm3+。通过调节各离子掺杂浓度，产品在特定波长的发光已得到优化。表面包覆的二氧化硅或PEG使纳米颗粒具有良好的亲水性，可以直接分散在水介质中。产品粒径均一，发光量子效率高，光稳定性好。该系列产品可与生物分子共价连接，用于荧光成像、生物检测、免疫分析，以及抗癌药物和生物分子的光控远程释放等。 This series of products contains amino functionalized 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 silica coating or PEG coating.The UCNs are of high quantum efficiency and very photostable. After proper surface modification and functionalization, the products can be used for fluorescence imaging, biodetection, immunity analysis and photoactivation of anti-cancer drugs and biomolecules
