Nano Crystal Coated LEDs

LED Building

Some reports say that now nothing can stand in the way of LEDs. With the nanocrystal coating, the LEDs are more efficient than the fluorescent light, are warmer and produce a very beautiful white light. These LEDs are greener considering the fact that a quarter of the electricity in U.S. is used by illuminated buildings and we all know that the electricity comes from coal power plants which pollute through greenhouse gas emissions.

Current commercial LEDs are based on blue LEDs, but coated in phosphorus they change into an yellow glow. According to Hilmi Volkan Demir from the Bilkent University in Ankara, Turkey, the color possibilities are infinite with the nanocrystal coating: “Using combinations of nanocrystals, one can generate any emission spectrum as desired”.
