Description:

Optoelectronics is the combined used of electronics and light. Solution-processed halide perovskites have shown great potential as the building blocks for the next generation of low-cost, high-performance optoelectronics and the next generation of LEDs. LED technology is rapidly advancing and there is a need for new materials with remarkable performance. 

One novel solution is LEDs that use MAPbBr3 as the emitter. These LEDs are high performing but are inherently unstable. Dr. Gao and his team have created all inorganic perovskites which are more stable both thermally and chemcially. This new material does not limit the performance of LEDs and shows the highest brightness among all perovskite LEDs demonstrated thus far. Furthermore, the synthesis creates films with incredibly small grain sizes which improves the smoothness of the films. This new material has the potential to revolutionize LEDs.

Advantages

  • Excellent performance including brightness and efficiency
  • Low-cost
  • High-stability
