Web7 mrt. 2024 · Ultraviolet (UV, λ<400 nm) light is essential for various photochemical reactions, but its intensity in the solar spectrum is very low, and light sources that artificially generate high-energy UV light are inefficient and environmentally unfriendly.A solution to this problem is photon upconversion (UC) from visible (vis, λ>400 nm) light to UV light. Web16 apr. 2024 · For example, the UV-visible spectrum of blood shows a prominent absorption peak at 415 nm. 15 If a blood spattered surface is observed with monochromatic light with this wavelength, the blood spots will appear as dark regions, because they will absorb all the radiation impinging upon them.
