What is a quantum dot?

What do quantum dots look like, and how are they changing entertainment, healthcare and security? Applied nuclear physics lecturer Dr Caroline Shenton-Taylor tells us how they work and why she loves them. 

What are quantum dots?

Quantum dots are tiny specks of material, so small that some people say they have no dimensions. They exist as points of materials, typically 1/10,000 the size of a human hair.

Materials this small are called nanoparticles.
