Technique Regulates Light in Liquid

Barbara Grant

Chemists at Utrecht University and Philips Research have developed a technique to regulate light flow through a liquid using an electric field. Based on the phenomenon of light absorption by "nanorods" -- metal particles that measure 12 to 22 nm in diameter and 40 to 730 nm long -- the technique allows scientists to select the amount of light passing through the liquid by applying an electric field to change the rods' orientation. The aqueous dispersion of gold rods has a color that is dependent upon the rods' aspect ratio, or length divided by diameter. An aspect ratio of 8.9 will yield...Read full article
