Application

Our rare earth doped upconversion nanoparticles possess inorganic fluoride host lattices and can be easily excited with near-infra-red (NIR: 980 nm) light source. These Cd-free nanoparticles exhibit characteristic emission peak and are well suited for applications as luminescent biological labels and as spectral converters for increasing solar cell efficiency cell.
