Lighting up the World

Incandescent light bulbs are very inefficient in transforming energy into light. Since about 20% of the world’s total electricity consumption is used for lighting, a new and more efficient light source has to be developed. One solution is solid-state lighting, which employs light-emitting diodes (LEDs) made from semiconducting materials. The image shows the cathodoluminescence (CL) from an LED excited by the electron beam of an FEI Quanta 250. CL imaging helps to understand the properties of these LEDs and gives valuable insight into prevalent defects, such as the ring-shaped defect in the image, in order to improve the devices.
