Green LEDs News
The Shrinking Green Gap: Trends in Solid-State Green Emitters
Dec 7, 2018 — Human eyes are most sensitive to light in the yellow-green region of the visible spectrum. This well-known fact is a result of the way mammalian eyes, and for that matter the eyes of all land-dwelling animals, have evolved from those of aquatic...
Method increases green LED light output
TROY, N.Y. – In a step toward the development of LED televisions and displays, researchers have devised a method for manufacturing green-colored LEDs with greatly enhanced light extraction, internal efficiency and light output. Scientists at Rensselaer...
RPI Closing 'Green Gap' in LEDs
RENSSELAER, N.Y., Aug. 28, 2006 -- Researchers from Rensselaer Polytechnic Institute (RPI) has received $1.8 million in federal funding to improve the energy efficiency of green LEDs. As part of the US Department of Energy’s (DOE) Solid-State Lighting Program, the team aims to close...
Green LEDs Take a Semipolar Route
Feb 1, 2006 — Green LEDs, which comprise thin films of GaN doped in various ways, present problems when the upper films are grown along a polar direction of the GaN crystal. For example, strong polarization-induced electric fields are produced and lead to a...
