For blue light, nitride diodes achieve external quantum efficiencies in excess of 65%, i. e., one photon is emitted for approx. 2/3 of the electron-hole pairs injected into the diode. For red light, phosphor diodes achieve efficiencies of approx. 50%. However, so far no highly efficient monochromatic LEDs have been available for the `yellow gap` at around 560 nm. Now researchers with Philips Lumileds have developed a monochromatic nitride diode that closes this gap. http://www.physorg.com/news167555795.html Physics Thu, 23 Jul 2009 08:17:44 EST news167555795 (PhysOrg.com) -- The race is on for a successor to the popular 'flash' memory used in portable devices.
