Improving LEDs with quantum dots

Getting lights to last for longer and remain bright is an important backdrop to furthering the development of many modern technologies. A type of quantum dot could well hold the answer to driving such improvements. Researchers have been studying quantum dots in order to find a low-energy means of reproducing light in every color visible to the human eye and at a very bright luminescence. Given the success of the research, the quantum dots should provide the basis for a new generation of light-emitting diodes. The research comes from an international research team led by ETH Zurich and IBM Research Zurich. At the basis of the technology is a class of nanocrystals that have the ability to shine a range of very bright colors. The nanocrystals are formed from caesium lead halide compounds.
