The fluorescent materials are Lanthanides. They are
mixed into the ink that makes the taggants zone on the
bill.
The Lanthanide ions are embedded in the crystal lattice
of the nanoparticle so their fluorescent secondary
photons are numerous and distinct.
The high brightness intensity points are called peaks,
and the totality of all the peaks in the range from
200nm to 1500nm wavelength is called the “peaks
profile”.
It’s like a picture of mountain peaks in that it is
highly recognizable if you know what to look for. It’s
like the mountains, the shape of the peaks profile
tells you where you are, or in this case, the shape of
the peaks discloses the taggants that compose the
fluorescent tag on the bill.
