Quantum dots (QD) are very small semiconductor particles, only several nanometres in size, so small that their optical and electronic properties differ from those of larger particles. They are a central theme in nanotechnology.
Quantum dotsâ ability to precisely convert and tune a spectrum of light makes them ideal for LCD displays. From smartphones to tablets to TVs, we can make all the colors we see even better by remixing white light into red, green and blue components.
