Plasmonic pixels become dynamic

NanoWerk.com - Mon, 03/04/2019 - 04:46
Researchers demonstrate a display pixel that can switch on and off at least 1000 times faster than pixels that use conventional liquid crystal materials. They show that plasmonic gold nanorods - which interact very strongly with light - can be aligned using electric fields, and they use this alignment to control the amount of light that can pass through the pixel. By engineering the dimensions and material structure of the nanorods, the scientists design pixels that work with different colors of light, both visible and infrared.
