Phosphor (Energy Converter)
Inorganic phosphor materials
“Classical” inorganic phosphors usually consist of a host lattice with activator ions doped into it in small concentrations, typically a few mole percent or less.
Host lattice & Activator ion
1st type : weak interaction (Ln3+)
2nd type: strong interaction ( Mn2+, Eu2+, Ce3+, Pb2+,Sb3+, Ce3+, MoO42-, NbO43-)
Activator (+ Sensit
The Fog Script
Almost midnight.
Enough time for one more story.
One more story before
just to keep us warm.
In five minutes,
itll be the st of April.
One hundred years ago on the st of April,
out in the waters around Spivey Point,
a small clipper ship drew toward land.
Suddenly, out of the night,
the fog rolled in.
For a moment, they could see nothing,
not a foot ahead of them.
And then, they sa
