Indeed, tiny grains of salt!

But while this piece is hype, quantum dots have in the past,
historically, actually turned out to be the "best" solution
in about 50% of the hyped applications. I've used the things
in my research, and they do, in some cases, work miracles.

One advantage is the they have a sharp red-edge absorption
cutoff, so the blue channel would need only a UV removal
filter, the green channel only a yellow filter, and the
red channel only a red filter. No IR filter needed.
