fotóindukált

Fotóindukált refers to a process or phenomenon that is triggered or caused by light. The term originates from Greek roots, with "foto" meaning light and "indukált" meaning induced or caused. In scientific contexts, it describes a reaction, change, or event that occurs when a substance or system is exposed to photons, the fundamental particles of light.

This can manifest in various ways across different fields. In chemistry, photochemically induced reactions are common, where light provides the activation energy necessary for a chemical transformation to occur. Photosynthesis in plants is a prime biological example of a photoinduced process, where light energy is converted into chemical energy. In materials science, photoinduced changes can lead to alterations in the optical, electrical, or structural properties of materials, such as photochromism, where materials change color upon exposure to light. The field of optoelectronics heavily relies on photoinduced effects for the operation of devices like solar cells and photodiodes. Understanding photoinduced phenomena is crucial for developing new technologies and for comprehending natural processes that are governed by light.
