Anybody heard of this?
From this week's Nature: Nature 454, 256 (17 July 2008)
....
Wooseok Ki and Jing Li of Rutgers University in Piscataway, New
Jersey, have discovered a new type of semiconducting material that
emits white light when illuminated by a blue LED. It consists of
stacked sheets of cadmium sulphide that have amine molecules attached
to their top and bottom surfaces.
The brightness is improved by adding a little manganese. Next the
researchers will need to see if the white emission can be driven
purely by electricity.
