Definição de Luz Ultravioleta. In interactions with matter, visible light primarily acts to elevate electrons to higher energy levels. UV-LEDs require unique and delicate production process. Further conjugation can absorb longer wavelengths and, like anthracene, begins edging into visible light, which as a result has a yellow color and more transitions in the UV-VIS spectrum.
