Scientists in Taiwan converts tree into streetlights using gold nanoparticles

Streetlights are an important part of our lives since they enlighten our ways so we care for them. But they also use alot of energy to light up. Recently a group of scientists in Taiwan discovered, accidentally when scientists were looking to create high-efficiency lighting similar to LED technology without using toxic chemicals such as phosphor powder, that by placing gold nanoparticles amung the leaves of trees, causes them to give off a luminous reddish glow. This idea is very cool and eco-friendly, less cost and more beneficial

Professor Shih-Hui Chang said:
Light emitting diode (LED) has replaced traditional light source in many display panels and street lights on the road. A lot of light emitting diode, especially white light emitting diode, uses phosphor powder to stimulate light of different wavelengths. However, phosphor powder is highly toxic and its price is expensive. As a result, Dr. Yen-Hsun Wu had the idea to discover a method that is less toxic to replace phosphor powder. This is a major motivation for him to engage in the research at the first place.
