Upconverting Nanoparticles:
Upconverting nanoparticles are a distinct type of optical nanomaterials doped with lanthanide ions featuring a wealth of electronic transitions within the 4f electron shells. These nanoparticles have the capability to convert two or more low-energy photons into one high-energy photon. Their excellent chemical stability, large stokes shifts, narrow bandwidth, absence of photobleaching and photoblinking, and low toxicity make them promising candidates for bioanalytical and biomedical applications.

Our Products
Dense silica amino coated upconverting nanoparticles combine the unique optical properties of upconverting materials with the functional advantages of a silica shell and amino surface groups. They can be widely used in biomedical fields, especially in applications requiring deep tissue penetration and minimal background fluorescence.
Our products are doped with lanthanide ions in which ytterbium (Yb3+) acts as the sensitizer and erbium (Er3+) or thulium (Tm3+) acts as the activator. Ytterbium absorbs near-infrared light efficiently and transfers energy to the activators, which then emit visible or ultraviolet light.
