Wouldn’t it be great if we could control individual atoms? Just imagine if we could “turn” them on and off to store bits of information, make them light up with different colors, or control them in all kinds of other ways. Unfortunately, that’s not possible—but scientists have discovered how to do the next best thing with quantum dots, which are sometimes known as “artificial atoms.” Simply speaking, they’re examples of nanotechnology: groups of atoms made from semiconductor materials that promise to revolutionize everything from home lights and computer displays to solar cells and biological warfare detectors. What are they and how do they work? Let’s take a closer look!
What are quantum dots?
A quantum dot gets its name because it’s a tiny speck of matter so small that it’s effectively concentrated into a single point (in other words, it’s zero-dimensional).
Nanoco Group PLC (LON:NANO) leads the world in the research, development and large-scale manufacture of heavy metal-free nanomaterials for use in displays, lighting, vertical farming, solar energy and bio-imaging.
