Many of us are familiar with the light-emitting diode (LED), a technology that now provides the most efficient lighting option to date. LEDs in a diverse range of colours are widely used for lighting across application sectors. But over the course of the last 10 years, one prospective technology has threatened to rock the boat of LED lighting: the quantum-dot LED (QD-LED).
QD-LEDs are based on quantum-dot technology, comprised of quantum dots (QDs), semiconductor particles just a few nanometres in size. Because of their small domain, their behaviour is governed by quantum mechanics. By ‘exciting’ quantum dots using electrical currents or driving radiation, they can be induced to emit light, the colour of which is based on the size of the QD.
