The brightest quantum-dot LEDs yet made could provide lighting for displays that are clearer and richer in colour, as well as being cheaper to make, than existing ones.
The devices could be used to make better displays for mobile phones and PDAs, and to light larger flat-panel TV screens, say researchers based in China and the US.
Quantum dots are nanoscale semiconductors that confine electrons in three dimensions. In this case, the quantum dots have a cadmium selenide core and a zinc sulphide "shell". Electrons are excited to higher energy levels in the core and the shell, then fall into the empty spaces, or "holes", left behind. The dot then forms an "exciton" and emits a particle of light.
