Electroluminescence

Electroluminescence is the process where materials emit light in response to an electric current or electric field. When electricity passes through certain substances, it excites their atoms or electrons, causing them to release energy as visible light as they return to normal. This phenomenon is used in devices like LED lights and digital displays, offering energy-efficient illumination and clear visuals. Essentially, electroluminescence converts electrical energy directly into light through a controlled electronic reaction within the material.
