New materials for high efficiency organic solid state lighting
March 30, 2006A new organic molecule developed by Pacific Northwest National Laboratory scientists may significantly improve the efficiency of organic solid state lighting. Direct conversion of electricity to light in "solid state" thin films of organic molecules occurs in organic light emitting devices which can be far more efficient than conventional "incandescent" light bulbs.
In an OLED, light emitting molecules harvest positive and negative charge carriers from oppositely charged electrodes to create excitons, which collapse to give light emission. By using organometallic phosphors, a photon can be emitted for every electron used so there is no wasted current.
But until now, no good host materials were available to transport the charge to blue phosphorescent light emitters. And, without an efficient blue component, it is not possible to generate the high quality white light required for indoor lighting. The PNNL team is solving this problem by linking small organic molecules together using inorganic "phosphine oxide" connecting units to make larger molecules that transport charge but do not interfere with the blue light emission process.
PNNL researcher Paul Vecchi will present his results Thursday, March 30.

Researchers lay out vision for lighting 'revolution'
A "revolution" in the way we illuminate our world is imminent, according to a paper published this week by two professors at Rensselaer Polytechnic Institute.
New coating is virtual black hole for reflections
Researchers have created an anti-reflective coating that allows light to travel through it, but lets almost none bounce off its surface. At least 10 times more effective than the coating on sunglasses or computer monitors, the material, which is made of silica nanorods, may be used to channel light into solar cells or allow more photons to surge through the surface of a light-emitting diode (LED).
Nobel Prize Winner says that to take Advantage of all the Government's work in Improving the Science Base it must act now to Bolster Chemistry Student Numbers
Nobel Laureate and new President of the Royal Society of Chemistry, Professor Sir Harry Kroto today issued a stark warning of the economic consequences of the failure to attract more Chemistry students. He said that the present number of around 3000 new undergraduates per year must be increased by at least 50 per cent if the UK is to retain a leading role in developing and implementing the most exciting and strategically promising cutting-edge technologies of the 21st century. This aim should be attainable as Chemistry has never been more intellectually exciting or technically more important. This Government has worked hard to improve the science base but these efforts wou

Introduction to Solid-State Lighting by Arturas Zukauskas (Author), Michael S. Shur (Author), Remis Gaska (Author) A thorough reference that sheds light on the promising field of solid-state lighting Solid-state lighting is a rapidly emerging field. Light Emitting Diodes are already used in traffic signals, signage/contour lighting, large area displays, and automotive applications. But its greatest future lies in the possibility of applying solid-state lamps to general lighting. Solid-state lighting promises to reduce energy consumption as much as fifty percent, cut down on carbon-dioxide emission, and even spur the development of a completely new lighting industry. Giving this important emerging field the attention it deserves, Introduction to Solid-State Lighting comprehensively covers: * The history of lighting * The characterization of visible light *... |
