![]() ![]() Bigger dots produce longer wavelengths, lower frequencies, and redder light smaller dots produce shorter wavelengths, higher frequencies,Īnd bluer light. More closely) spaced energy levels, so they give out lower frequenciesĪrtwork: Quantum dots are just a few nanometers (nm) wide. Higher frequencies (and shorter wavelengths). ![]() Proportional to the energy, smaller dots with higher energy produce (crudely speaking, that's the minimum energy it takes to free electrons so they'll carry electricity through a material), so it takes more energy to excite it because the frequency of emitted light is Small dots make blue, with intermediate-sized dots producing green light (and theįamiliar spectrum of other colors too). While the smallest dots make shorter wavelengths (and higherįrequencies) in practice, that means big dots make red light and The biggest quantumĭots produce the longest wavelengths (and lowest frequencies), The same material (say, silicon) will give out differentĬolors of light depending on how big they are. Quantum dots do the same trick-they also have quantized energy levels-but dots made from However, the energy levels are governed by the size of the dot rather than the substance from which it's made. Quantum dots produce light in a similar way because the electrons and holes constrained inside them give them similarly discrete, quantized energy levels. The color of the light depends on the energy levels and varies from one atom to another. When it returns, the energy is given out as a photon of light (3). After absorbing energy (1), an electron inside an atom is promoted to a higher energy level further from the nucleus (2). In atoms have set values in other words, they are quantized.Īrtwork: How atoms make light. All this is possible because the energy levels The rule is that different atoms give outĭifferent colors of light. While sodium looks yellow, and that's because of the way their energy Looks green when you excite its atoms by holding them in a hot flame, The color (wavelength andįrequency) of light an atom emits depends on what the atom is iron Lower level, the atom emits a photon of light with the same energy School-level physics tells us that if you give anĪtom energy, you can "excite" it: you can boost an electron Quantum dots can be precisely controlled to do all kinds of useful things. And although they're crystals, they behave more like individualĪtoms-hence the nickname artificial atoms. Material that's neither really a conductor nor an insulator, but canīe chemically treated so it behaves like either). They're made from a semiconductor such as silicon (a Quantum dots are crystals a few nanometers wide, so they're typicallyĪ few dozen atoms across and contain anything from perhaps a hundred to a few (think rungs on a ladder), a bit like individual atoms. Inside it that carry electricity (electrons and holes, which are places that are missing electrons) are trapped ("constrained") and have well-defined energy levels according to the laws of quantum theory Speck of matter so small that it's effectivelyĬoncentrated into a single point (in other words, it's zero-dimensional). I hope you will enjoy it.A quantum dot gets its name because it's a tiny The link to the live TV server is given below.
