Researchers developed a simple method to create special zinc oxide (ZnO) structures shaped like mushrooms with enhanced light-emitting properties. By adjusting the ratio of methanol to water in a heating process and using a special zinc-based chemical as a building block controller, they achieved structures with specific crystal surface exposures. These twined-mushroom structures showed significantly brighter light emission, making them promising candidates for use in light-emitting devices that require single-color output.
