Photobleaching 뜻
WebJun 2, 2024 · Photobleaching refers to the lightening of the hair through prolonged exposure to sunlight. The photobleaching process gradually turns dark brown hair into light brown hair. It can even lighten light brown hair into sun-kissed blonde hair. You may not have noticed it before, but your hair may be photobleached from spending time outdoors.

Did you know?
In optics, photobleaching (sometimes termed fading) is the photochemical alteration of a dye or a fluorophore molecule such that it is permanently unable to fluoresce. This is caused by cleaving of covalent bonds or non-specific reactions between the fluorophore and surrounding molecules. Such irreversible … See more • Ozone depletion See more • Introduction to Optical Microscopy an article about photobleaching • Viegas MS; Martins TC; Seco F; do Carmo A (2007). "An improved and cost-effective methodology for the … See more Web3.1 Introduction to photobleaching. In the ideal case, an incident photon of appropriate wavelength is absorbed by a fluorophore, promoting the fluorophore to an excited state; subsequently, the fluorophore relaxes down to its ground state by emitting a photon. In reality, it is possible that the incident photon can break the fluorophore with the result that …
