Nanoparticles make leaves glow

glowing leavesCan street lights be replaced by trees? Taiwanese scientists believe that they can using gold nanoparticles to induce luminescence in leaves.

Yen Hsun Su and coworkers at Academia Sinica and the National Cheng Kung University in Taipei and Tainan have tackled this problem by synthesising gold nanoparticles shaped like sea urchins and diffusing them into plant leaves to create bio-LEDs.

One Response to “Nanoparticles make leaves glow”

    The article does not come even close to show that “Nanoparticles make leaves glow”. The only visible light emitted is under UV illumination and the quantum yield of gold particles is extremely low so this is a very inneficient way of turning blue photon into red photons.
