此系列产品为油溶性上转换纳米颗粒,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。产品粒径均一,发光量子效率高,光稳定性好。经过表面改性后可用于荧光成像、生物检测、光动力疗法,以及抗癌药物和生物分子的光控远程释放等。
This series of products contains oil dispersible 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 UCNs are of high quantum efficiency and very photostable.
After proper surface modification and functionalization, the products can be used for fluorescence imaging, biodetection, photodynamic therapy and photoactivation of anti-cancer drugs and biomolecules.
