Bright, efficient and stable LEDs made using nanocrystals of perovskite material
What They Say Nature has published a paper that describes new perovskite LEDs (PeLEDs) made from perovskite nanocrystals (around 10nm) that have a coating of benzylphosphonic acid (BPA) via a ‘simple reaction’. The article said: The BPA shell passivates the undercoordinated lead atoms by forming covalent bonds, and thereby greatly reduces the trap density while maintaining … Read more
