Product Description
This series of products contains ligand-free 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 oleates have been removed from the nanoparticle surface through treatment with diluted hydrochloric acid, rendering UCNs dispersible directly in water and ethanol. 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.
