Fotokeemilist

Fotokeemilist refers to chemical reactions that are initiated by the absorption of light. This phenomenon is fundamental to a wide range of natural and artificial processes. In nature, photosynthesis is a prime example of a fotokeemiline process, where plants use light energy to convert carbon dioxide and water into glucose and oxygen. Another natural example is the vision process in animals, where light triggers a chemical change in photoreceptor molecules in the eye, leading to the perception of sight.

In artificial applications, fotokeemilist principles are employed in photography, where light exposure causes chemical changes on photographic film or sensors to capture images. Ultraviolet curing, used for rapidly hardening inks, coatings, and adhesives, also relies on fotokeemiline reactions initiated by UV light. The development of solar cells, which convert sunlight directly into electricity, is another significant application of fotokeemilist. Photochemistry also plays a role in areas like photodynamic therapy for cancer treatment, where light activates drugs to destroy cancer cells. Understanding and harnessing fotokeemilist allows for the development of new materials, technologies, and solutions across various scientific and industrial fields.
