Natural light to reinvent bulbs

`A natural light source that could put the traditional light bulb in the shade has been invented by US scientists. [..]

Previous attempts to make OLEDs like this have largely failed to make an impact because traditional phosphorescent blue dyes are very short lived.

The new polymer uses a fluorescent blue material instead which lasts much longer and uses less energy.

The researchers believe that eventually this material could be 100% efficient, meaning it could be capable of converting all of the electricity to light, without the heat loss associated with traditional bulbs.’
