A US-based team of scientists claims to have invented a material that releases over two weeks of night-vision light after just one minute’s exposure to the sun. The University of Georgia team says the near-infrared emitting substance could offer the military “secret” illumination at nighttime. It says the all-weather material could also revolutionise diagnostic medicine. The details are published in the latest issue of the Nature Materials journal. The material combines the well-known near infrared-light emitter trivalent chromium ion with zinc gallogermanates – a complex oxide compound.
