          Dot Quantum, QD, a new concept of nano scale semiconductor light-emitting particles, was discovered in 1981. Elements not only limited to several elements of II - VI (BAS, CdTe, etc.), III-V (GaAs and InGaAs), I - III - VI (AgInS2). In the future there will be more system will be developed.
          Quantum dot is the basic material of quantum dot LED (QLED) luminescence. Light has two forms: A is used as optical conversion layer effectively absorbs part of the blue light emitting wavelength in the visible light range precise adjustable light of different colors; the second is using the electric emitting form, coated on the film between the electrodes and the light, to implement qled luminescence in GaN based LED.
Quantum dot LED as lighting (qled) it has three virtues: A, capable of launching a full spectrum, which covers the visible and infrared region; second, they can in the quantum confinement luminescence properties, and release the shade of smaller bandwidth and emission wavelength half width is below 20 nm, thus showing a more saturated color;, quantum efficiency can reach 90%. Later there will be more room for improvement.
With the increase of the preparation of quantum dot technology, especially spectra of quantum dots with size can be, large Stokes shift, light emitting efficiency is high, light stability and a series of unique optical properties, making it become the focal point of research in recent years, and great progress has been made.
          At present, the quantum dot LED (QLED) light source is also born in the laboratory. And more forecast shows that the next 15 years, the quantum dot LED will light up the world.
          Quantum dots have a wide range of commercial impact on LED technology, the current, improve the manufacturing process and improve the profit is the focus of the research area. According to reports, the Oregon State University researchers have demonstrated the manufacturing technology of a new kind of quantum dots, which can not only ensure that made the size and shape of the quantum dot consistent, but also the more accurate color control, may mean that the advent of a new era of LED lighting.
