Caption: Quantum dots. Coloured scanning electron micrographs (SEMs) showing a well-made quantum dot (top) and a poorly-made quantum dot (bottom). Quantum dots are nanocrystals of semiconductor material that emit photons when excited. The size of the quantum dot can be tuned during manufacturing to produce a certain wavelength of photon emission. Quantum dots have a number of applications including use in light emitting diodes (LEDs), quantum computing, solar panels and labelling biological tissue.
