When UV light hits a quantum dot, its electrons are raised to a higher energy state. When the electrons fall back to their base level the difference in energy between the two states is released as light.<\/p>\n<p>They are referred to as quantum dots for two reasons. First, they exhibit quantum properties thanks to how they confine electrons within themselves. Quantum effects are those sub-atomic laws of physics that scientists are still trying to fully understand, but we can already apply them in devices like quantum computers.<\/p>\n<p>They\u2019re referred to as dots because they are so small, that they are virtually zero-dimensional. In other words, they are a single point with no width, length, or height. Well OK, they are a few dozen atoms across, but they are so close to being zero-dimensional points that the wacky laws of <a rel=\"nofollow noopener\" target=\"_blank\" href=\"https:\/\/en.wikipedia.org\/wiki\/Quantum_mechanics\">quantum mechanics<\/a> come into play.<\/p>\n<h2 role=\"heading\" aria-level=\"2\"><span class=\"ez-toc-section\" id=\"What_Makes_Quantum_Dots_So_Useful\"><\/span>What Makes Quantum Dots So Useful?<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<figure style=\"width: 650px\" class=\"wp-caption alignnone\"><img loading=\"lazy\" decoding=\"async\" class=\"size-full wp-image-809032\" data-pagespeed-lazy-src=\"https:\/\/www.howtogeek.com\/wp-content\/uploads\/2022\/05\/quantum-dot-plastic-tubes.jpg?trim=1,1&amp;bg-color=000&amp;pad=1,1\" alt=\"Plastic tubes with quantum dots of perovskite nanocrystals, luminescing with all colors of the rainbow under ultraviolet radiation.\" width=\"650\" height=\"366\" src=\"\/pagespeed_static\/1.JiBnMqyl6S.gif\" onload=\"pagespeed.lazyLoadImages.loadIfVisibleAndMaybeBeacon(this);\" onerror=\"this.onerror=null;pagespeed.lazyLoadImages.loadIfVisibleAndMaybeBeacon(this);\"\/><figcaption class=\"wp-caption-text\"><span class=\"imagecredit\"><a rel=\"nofollow noopener\" target=\"_blank\" href=\"https:\/\/www.shutterstock.com\/image-photo\/plastic-tubes-quantum-dots-perovskite-nanocrystals-700118482\">Leo Matyushkin\/Shutterstock.com<\/a><\/span><\/figcaption><\/figure>\n<p>Quantum dots behave like atoms that have been excited, but they differ in one fundamental way. The light you get out of an atom or a quantum dot is equal to how much energy was absorbed and released, which determines the wavelength and therefore color of the light. However, one type of atom (e.g., iron, sodium) will always emit the same wavelength of color.<\/p>\n<p>Quantum dots, on the other hand, can all be made from the same semiconductor material, but produce different wavelengths depending on their size. The larger the dot, the longer the wavelength, and vice versa. So bigger dots tend towards the red end of the spectrum and smaller ones to the blue end.<\/p>\n<p>This attribute of quantum dots means that you can precisely control colored light emission making bright, accurate colors.<\/p>\n<h2 role=\"heading\" aria-level=\"2\"><span class=\"ez-toc-section\" id=\"How_to_Make_Quantum_Dots\"><\/span>How to Make Quantum Dots<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>Quantum dots have a precise structure because they\u2019re crystals.\u00a0 The silicon wafers that our microchips are made from are likewise grown as crystals, which self-organize into atomic patterns. This is why we can make quantum dots with precise structures at the nano-scale. If we had to build them one atom at a time, they wouldn\u2019t be very practical!<\/p>\n<p>They can be made by firing beams of atoms at a substrate to build crystals, you can fire ions (free electrons) at your semiconductor substrate, or by using X-rays. Quantum dots can also be created using chemical processes, and even using biological processes.

Today\u2019s silicon-based solar cells are already quite efficient at gathering energy from light, but because quantum dots can be \u201ctuned\u201d to absorb light from various parts of the electromagnetic spectrum, they could bring about much more efficient solar panels. Not only would these panels be more efficient, but they\u2019d also be cheaper to produce since the process to make the necessary quantum dots is relatively simple.<\/p>\n<p>Theoretically, you could make a pure quantum dot solar cell, but they can also be used in hybrid solar cells.

They can even play a role in the early diagnosis of tumors.<\/p>\n<p>Quantum dots may also be the key to photonic computing, as electrical circuits get so small that quantum effects make the flow of electrons through them impossible. computing with photons may be the next step.
