Ordered nanocrystal arrays may provide a new platform to study and tailor the light-emitting properties of silicon

23-11-2012

US scientists at the University of Texas at Austin and Cornell University have fabricated the first ordered arrays of silicon nanocrystals reported to date. Brian A. Korgel and colleagues developed a new chemical method to generate tiny silicon crystals—or quantum dots—with precisely ...

The dream of low-cost, energy-efficient lighting on a big scale becomes tangible thanks to barrier coating systems for flexible OLEDs developed by Fraunhofer researchers

16-04-2010

Organic light-emitting diodes (OLEDs) are nowadays synonymous with next generation lighting, which could replace common light-bulbs in a couple of years. They convert electricity very efficiently into light of high quality. However, existing OLEDs on the market are costly and mostly deposited ...
