Zhengwei Pan and Feng Liu stand in a darkened room, using nothing but their recently invented ceramic discs that emit infrared light as a source of illumination. The image was taken using a digital camera with a night vision monocular. Their phosphorescent material was also mixed into the paint that was used to create the UGA logo behind them. There is no other source of illumination in the room; without the aid of a night vision device, the image would be completely dark. Credit: Zhengwei Pan/University of Georgia, USA.
