The 5 techniques used in the field of LED forced Girton is not the same

Deng Xiaoping said: "science and technology is the first productive force". It is true that "social development depends on science and technology". The development of LED lighting industry, also need to seek a breakthrough, constantly moving, not be complacent. August has arrived, since in recent days, good news are the breakthrough of new technology at home and abroad of the small, so today decided to introduce for everybody one by one, all feel this change rapidly progress in science and technology.

Ultra fast LED light emitting device

Researchers at the Duke University have recently developed a LED light-emitting device that can be turned on and off 90 billion times in one second, which can be used as the basis of optical computing technology.

Grilled steak: every day now we cannot do without the intelligent mobile phone, to charge every day, but many people may not know, a small battery inside with billions of transistors, can be used in electronic switching for billions of times per second for power supply. Recently, researchers at the Duke University have developed a LED light emitting device that can be turned on and off for 90 billion times in one second, which can be used as the basis for the application of optical computing technology. Next, as long as the researchers continue to develop light source capable of quickly opening and closing, so that the micro chip can use photons instead of electrons to process and transmit data, the computer running speed can be greatly improved. According to reports, although the laser can meet this requirement, but due to the existence of excessive energy consumption and the excessive volume of the launch device, is not suitable for working inside the computer. Now, the rapid development of the Duke University light-emitting devices, indicating that the researchers from the production of suitable for the use of light computer light source is a step closer. Although the revolution is not successful, success is a step closer, really gratifying.

Two, phosphorus light-emitting materials

Australian National University scientists recently discovered in the study of the thin layer of phosphor luminescence characteristics, is expected to ultra-thin and ultra light solar (PV) batteries and light-emitting diode (LED) applications to open a line of dawn.

Grilled a steak: with respect to some time ago, a fire of graphene, "phosphorene" (the name) I'm afraid to come a little strange. Compared with graphene, graphene is a more like silicon (Silicon) semiconductor, it is well known that silicon is the basis of electronic technology. The team of scientists created the graphene, is the use of graphene and won the Nobel prize in physics as a method, that is, the use of tape repeatedly in the form of black crystalline phosphorus stripped of the increasingly thin crystal layer. According to the researchers, because of the state of the surface of the phosphor can be minimized, it is different from the state of the surface and can not be used in thin silicon. The performance of phosphorus in thin layer is better than that of silicon. In addition to creating a more light than silicon semiconductor, phosphorus also has light emitting properties and thickness of different layers, to achieve a more flexible production. Due to the fact that the phosphor is light and thin, it creates opportunities for the production of many interesting devices, such as LED or solar cells.

Three, can emit white light laser

Scientists in the United States, for the first time, developed a laser capable of emitting white light. The researchers said that white light emitting diode (LED) brighter and more efficient, the future will play an important role in the field of lighting and wireless communications.

Grilled steak: has been widely used in various fields of laser, there has been a short board: only a single wavelength of light. In order to solve this problem, a white light laser. A team of researchers at the Arizona State University recently developed a novel nano sheet. The thin semiconductor is only 1/5 of the size of the hair, only the thickness of the hair of the silk, which has three parallel parts, each part can be issued red, blue, green, a color of the laser. When the primary colors "meet", a white laser. This latest research results, so that the laser alternative to LED as a mainstream light source and a step forward. Another important application of the study, or will include the field of visible light communication (LiFi), looking forward to the future, the indoor lighting system can also be used for communications. At present, the prevalence of "WiFi" is the use of radio waves, LiFi speed can reach 10 times more than WiFi. However, the strong in its own strong hands, a mountain and a high mountain, allegedly, the speed of white laser WiFi, may be based on LED's 10 to 100 times more than LiFi. Unfortunately, there are still a lot of obstacles to solve this kind of white light laser application in the actual lighting or display system. Or that, "revolution...... "

Four, can be color graphene LED

Recently, Tsinghua University has been able to make the color of graphene LED, this new type of LED breaks through the existing display device color synthesis, is expected to have a revolutionary impact on the display, lighting and communication technology.

Grilled steak: it says so many awesome technology research abroad, domestic scientists also not fuel-efficient lights. It is understood that the light-emitting diode (LEDs) light-emitting colors and wavelengths are determined by light-emitting materials, once the preparation is completed, the two properties are determined. Currently, the idea of using a LED to change the color of the light is hard to achieve. Recently, the Tsinghua University research team from two kinds of graphene produced a new luminescent material, the first time in proving the lighting system of graphene materials based on only a LED can adjust the different colors of light. The research team developed a flexible graphite
