Quantum dots

Quantum dots are minor particles or nanocrystals of a semiconducting substances with diameter ranging from 2-10 nanometers. The foremost mechanisms of interaction between quantum dots (QDs) of various types and organic molecules within the framework of the use of photo-physical properties of colloidal semiconductor nanoparticles for recognizing organic and biochemical compounds. The most seeming result of this is fluorescence, in which the nanocrystals can produce different colors determined by the size of the particles. The distinct, quantized energy levels of quantum dots connect them meticulously to particles than bulk materials and have resulted in quantum dots being named 'artificial atoms'. quantum dots can form any color of light from the equal materials merely by changing the dot size. Furthermore, because of the high level of control probable over the size of the nanocrystals formed, quantum dots can be altered during manufacturing to emit any color of light.
