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. |
