Up-conversion Luminescence

Lasers for Up-conversion Luminescence

Up-Conversion luminescence is within the long wavelength emission, continuously emitting wavelength which is shorter than the excitation light. Up-conversion luminescence is essentially an Anti-Stokes light, which means the radiation energy is greater than the absorbed light. Up-conversion materials are mainly solid compounds doped with rare-earth elements, it can absorb multiple low energy long wave though the metastable level characteristics of rare-earth primary color, so as to make the invisible infrared light that people can not see to visible light.

CNI provides 808 nm, 980 nm, 1532 nm and other wavelengths laser sources for up-conversion luminescence.

Applications:

Infrared detection in visible light of infrared excitation, biomarker, long afterglow luminous warning signs, fire path signs or the interior wall coating as a night light function and so on.

Application case:

Fudan Univeristy used CNI MDL-H-980 infrared laser for excitation source, and published article in Acta Physico-Chimica Sinica:
