Quantum dots (QDs) are nanocrystals typically 2 to 20 nanometers in diameter. They are most commonly made from semiconductor materials but can also be based on metallic or metalloid elements such as silicon. These structures, containing hundreds to millions of atoms, are also called "artificial atoms" because their electronic band gaps can be tuned by altering their size. Properties The extraordinary optical and electrical properties of quantum dots are explained by a phenomenon known as "quantu
