Quantum dot developments

Nature Photonics volume 3, pages 315–316 (2009)Cite this article

Liquid suspensions of semiconductor nanocrystals that can be printed or coated onto a substrate promise a new era of low-cost optoelectronics. The demonstration of infrared image sensors and displays based on this approach and fully integrated with silicon electronics suggests that the technology is maturing rapidly.

Vision is perhaps the most important way in which we interact with our environment, not only providing us with information on our surroundings, but also influencing how we live, work and feel every day. In an increasingly digital world, electronic capture, storage and presentation of images is of growing importance. As a result, the concept of high-performance image sensors and displays that can be mass-produced at very low cost is of great appeal.
