Korean boffins invent white LED

Blinded by the light


Boffins in Korea
claim to have produced the world's first purely white LED.

If the claims prove true then LEDs could replace compact fluorescent lighting (CFL) as the next thing to replace iridescent light bulbs. LED's use much less power than CFLs but are not as bright because they do not have anything that looks like pure white.

They are not so hot in tellies or computer displays either because boffins have to spend a lot of the time making LEDs look white when they are not. Soo-Young Park, a professor of organic materials for photonics at the Department of Materials Science and Engineering at Seoul National University in Korea, led the group. He claims to have engineered a molecule with one orange and one blue light-emitting material that produces a white light in the visible light spectrum when put together.

Tests showed that the new form of LED molecule is efficient, colour stable, and able to be reproduced. According to the current issue of Journal of the American Chemical Society which is in the Fudzilla loos at the moment to save on bog paper, Park claimed to have successfully synthesized and characterised, for the first time, a white-light-emitting single molecule dyad, consisting of two noninteracting chromophores showing excited-state intramolecular proton transfer.

We guess the marketing people have not had a hand in this statement.
