compound introduction
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。 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.
