UVszrést
UVszrést is a term used in theoretical and experimental discussions of photonics to describe a proposed ultraviolet-induced rearrangement process in certain organic materials. The concept centers on the idea that ultraviolet irradiation can drive selective structural changes that persist after exposure, thereby altering optical properties such as refractive index, absorption onset, and scattering behavior.
The basic mechanism proposed involves photoexcitation of specific chromophores, formation of short-lived radicals, and subsequent crosslinking
Mechanisms remain debated. Proposed pathways include excitation-induced radical formation, cascade crosslinking, and targeted rearrangements of conjugated
Status and challenges: UVszrést is not yet established as a robust, broadly reproducible effect. Reported results
Potential applications include UV-tunable optical coatings, protective layered films for plastics, and components in light-controlled photonic
