Wafer-thin gold flakes emit a faint glimmer after being hit with a laser, and researchers are beginning to perceive why. Gold flakes are broadly utilized in nanoscience, so the brand new data ought to give scientists extra management over chemical reactions helpful for vitality storage and catalysis.
Gold owes its dazzling lustre to the best way it displays mild. But ultra-thin gold flakes also can generate and emit their very own mild in a course of known as photoluminescence. This begins when the gold is …
