 Material Sciences Professor Yen-Hsun Su’s Research Featured on Cover of Applied Physics Letters In the film Avatar, the plants on Moon Pandora impressed the audience with their ability to glow and communicate. This might also be possible for the plants on Earth! As suggested in a recent study from the National Dong Hwa University, in plants' photosynthetic process in the natural world, optical signals can be transmitted between antenna dye molecules. Assistant Professor of Materials Science, Yen-Hsun Su and his research team, supported by the National Science Council and the University, studied bioluminescent materials and found that sea-urchin shaped ZnO nanostructures synthesized by chemical vapor deposition can tune and separate the incident white light into red light, green light, and blue light (i.e., different frequencies). ZnO is a nontoxic and biodegradable material, which can be applied to organisms as a biological quantum information processor or photonic computer chip for separating, inserting, and transmitting signals of frequency-specific light absorption and transformation in photosynthesis. If the incident lights contain multiple signals, the signals can also be inserted between antenna dyes. Thus, plants on Earth may not only glow but also serve as bio-information processors in the future. Professor Su’s article, ”Nanoantenna-like Properties of Sea-urchin Shaped ZnO as a Nanolight Filter” was published on September 24, 2012 and featured on the cover of Applied Physics Letters, a weekly journal published by the American Institute of Physics since 1962. With an Impact Factor of 3.844 in 2011, it is also the most highly cited journal in applied physics.
