Reporters learned from Nanjing University of Technology on the 27th that the team of academicians Huang Wei and Wang Jianpu innovatively designed and prepared a perovskite LED with a multi-quantum well structure, which is far more efficient and stable than the international peer-reviewed The other perovskite LED, for the perovskite materials and their research in the field of light opened up a new direction.
The team produced an external quantum efficiency of 11.7% for LED devices, which is by far the highest in the world for perovskite LEDs. This important research achievement was published on September 26 in the world's top academic journal Nature Photonics.
The current low efficiency OLED devices, lack of stability and high manufacturing costs and other issues, limiting the scope of the OLED to expand the application, and efficient perovskite LED process is more simple, low energy consumption, material affinity for its characteristics in the light The field has opened up a new research direction, its future in the future after industrialization, has a broader market prospects.
According to Professor Wang Jianpu introduction, they developed a highly efficient perovskite LED containing organic - inorganic hybrid perovskite materials, both organic and inorganic semiconductor materials advantages, with two "good": First, the usual inorganic LED LED Take point light, can not do the display, only the OLED can do the display, but perovskite LED is different from the traditional inorganic LED, you can do the display, and the color is more vivid. Second, the advantages of perovskite LED lighting applications is also obvious. Its a traditional LED indoor lighting point-like light-emitting surface light, so that the light is not glazing indoor, closer to natural light, increase comfort. Traditional inorganic LED can only do a small area, but the use of this result can be made into a large area similar to the ceiling, and compared with traditional inorganic light-emitting materials with low defect density, high luminous efficiency, color purity and other advantages.
Boride-based powders are commonly used in thermal spray applications due to their high hardness, wear resistance, and thermal stability.
