Quantum Dots

Some nanotechnology related news on the Economist:

"A NEW range of televisions from Sony is the first to use minuscule devices known as quantum dots to produce colours which are more vibrant than those which appear on a conventional liquid-crystal display (LCD). Quantum dots are crystals of semiconductor material just a few nanometres (billionths of a metre) in size. They could have a big future in lighting and display technologies, but are difficult and expensive to manufacture, and use toxic materials. However, Geoffrey Ozin, from the University of Toronto, Uli Lemmer, from the Karlsruhe Institute of Technology, in Germany, and their colleagues believe they have found a way to deal with these problems."
