These 5 technologies are not the same in the LED field.

Deng Xiaoping said, "science and technology are the first productive forces". It is true that "social development depends on science and technology, and the progress of science and technology depends on innovation". The development of the LED lighting field also needs to seek breakthroughs and keep moving. August has come, review the recent days, the new technology has made a breakthrough at home and abroad, the good news is frequent, so today, the small editor decided to come first for everyone to introduce one by one, to feel the rapid progress of science and technology.

1. Ultra fast LED luminescence equipment

Researchers at the Duke University recently developed a LED luminescent device that can open 90 billion times in 1 second clock, which can be used as a basis for optical computing.

Steak: now everyone can't leave smart phones every day, charging every day, but not many people know that a small battery has billions of transistors inside, using an electric power supply that can open billions of times a second. Recently, researchers at the Duke University have developed a LED luminescent device that can open 90 billion times in 1 second clock, which can be used as a basis for optical computing. Next, as long as the researchers continue to work hard to develop a fast open light source, the microchip can use photons to replace the electrons to process and transmit data, and the speed of the computer can be greatly improved. According to the introduction, although the laser can meet this requirement, but because of the problem of excessive energy consumption and too large volume of the launching device, it is not suitable for working in the computer. Now, the rapid luminescence device developed by the Duke University indicates that researchers are a step closer to making light sources for the use of light computers. Although the revolution has not been successful yet, it is a step closer to success, and it is really gratifying.

Two, phosphene luminescent material

Scientists at the State University of Australia have recently discovered the luminescence characteristics in the study of thin phosphorus thin layers, and are expected to open a glimmer of light for ultra-thin and ultra light solar (PV) batteries and light emitting diodes (LED) applications.

Pick a pick: relative to the previous period of fire a handful of graphene, the name "phosphorene", I am afraid to come a little strange. Compared with graphene, phosphene is a semiconductor more like silicon (Silicon). It is well known that silicon is the basis of current electronic technology. The scientists' team created the phosphene, the same way that graphene won the Nobel prize in physics, using tape to peel off more and thinner crystals in the black crystalline form of phosphorus. According to the researchers, because the surface state of the phosphene can be minimized, it is thick with the surface state and can not be used in light thin silicon. The performance of phosphene in the thin layer is better than that of silicon. In addition to making semiconductors that are lighter than silicon, phosphene also has luminescent properties and layers of different thickness, which can be more flexible in manufacturing. Because phosphene is light and thin, it creates opportunities for many interesting devices, such as LED or solar cells, which exhibit very promising luminescence properties.

Three. A laser that can make white light

For the first time, American scientists have developed a laser that can make white light. The researchers say that white light lasers are brighter and more efficient than light emitting diodes (LED), and will play an important role in lighting and wireless communications in the future.

Steak: a wide range of lasers have been used in many fields, and there has been a short plate: only a single wavelength of light is emitted. In order to solve this problem, a white light laser appeared. The research team at the Arizona State University recently developed a new kind of nanoscale thin slices. The size of the thin semiconductor is only 1/5 of the hair, with a thickness of only 1/1000 of the hair. It has three parallel parts. Each part can produce a laser in a color of red, blue and green. When the three colors "meet", there is a white laser. This latest research has made a step forward by making the laser instead of LED becoming the main source of light. Another important application of the study, or will include the visible light communication field (LiFi), looks forward to the future, indoor lighting systems or can also be used for communication. The current popular "WiFi" is using radio waves, and the speed of LiFi can reach more than 10 times as much as WiFi. However, the strong middle hand, a mountain and a mountain high, it is said that the speed of the white laser WiFi may be more than 10 to 100 times as much as LED based LiFi. Unfortunately, there are still a lot of obstacles to be solved to apply the white - light laser to the actual lighting or display system. Or that sentence, "revolution..."

Four. Coloring graphene LED

The Tsinghua University has recently made a TONABLE graphene LED, a new type of LED that breaks through the color synthesis of existing display devices, and is expected to have a revolutionary impact on display, lighting and communication technology.

Steak: there are so many powerful foreign scientists and researchers that domestic scientists are not an oil - saving lamp. It is understood that the color and wavelength of the light-emitting diode (LEDs) are determined by the luminescent material. Once the preparation is completed, the two attributes are determined. At present, the idea of using a LED to change the color of the light is difficult to achieve. Recently, the Tsinghua University team made new luminescent materials from two different forms of graphene. The first time it was shown in the luminescent system based on graphene material that only one LED could be used to adjust the light of different colors. The research team developed a coloured graphene LED, which covers all the colors of the visible light spectrum except dark blue and violet. It is also reported that the new LED has broken through the color synthesis of the existing display devices, and is expected to have a revolutionary impact on the display, lighting and communication technology. As the color of light varies with a specific chemical, such devices may also be used to prepare special sensors. It is no wonder that experts have given a very high evaluation: "this work is expected to develop new research directions in the field of light emitting devices", "this work is exciting and influential."

Five. The most powerful laser equipment in the world

Scientists at the Osaka University in Japan say the "LFEX" can produce a 20 million - billion - watt laser beam, which is the most powerful laser beam in the world.

Steak: "Star Wars 7. The awakening of force" is coming back. Friends who are familiar with this series of science fiction films are expected to be exposed to age. In any case, the "Star Wars fans" must also be impressed by the "dead star weapons". The "fast ignition laser (LFEX)", used by researchers at the Osaka University in Japan, can produce a 20 million - billion - watt laser beam, which is very much like the "dead star weapon" in a science fiction film. The researchers produced high energy output from low energy devices, emitting laser beams only through 1 micro seconds (one trillion seconds). In order to amplify the laser beam power, the energy will be applied to the glass panels of the 100 meter long LFEX equipment to be amplified step by step. It is understood that the 5 - World - watts laser beam can shoot down unmanned aerial vehicles (UAVs) of 1.6 kilometers away. Before that, the world's University of Texas made a 10 million - billion - watt laser, and the latest laser equipment from Osaka University in Japan could make a 20 million - billion - watt laser. The team also said that the future laser equipment will produce a 100 million - billion - watt laser. At present, LFEX laser equipment is also the main scientific research value, and it has not been put into practical application.
