Kirchner effect

The Kirchner effect refers to the phenomenon where certain chemicals or materials exhibit a change in their optical properties, such as absorption or transmission of light, when they are exposed to specific stimuli like light or electric fields. It often involves a reversible shift in color or transparency. This effect is important in applications like smart windows, sensors, and display technologies, as it allows materials to adapt their appearance or properties in response to environmental changes, enabling innovative control over light and energy use in various devices.
