Blue crystals to form basis of white LEDs

IT WAS Bob Colwell, an ex-chief architect at Intel, who tipped us off to the fact that if you add blue crystals to any product or even any headline, people will get jolly excited.

See Intel "speed of light" chips tainted by blue crystal hue.

Now nikkei.net reports that Sumitomo has started to make and soon will start to sell sapphire substrates as the basis for white LEDs.

According to the report, the sapphire substrates will be polished with silica granules with diameters of a not very considerable 100 nanometres.

The report said sapphire will help the white LEDs be brighter and samples are already being shipped. µ
