Everything You Should Know About UVC LED Light (2024 …

WebUltraviolet radiation is invisible energy in the wavelength range from 100 to 400 nanometers (nm). A nanometer is one billionth of a meter. UV radiation has a shorter wavelength and is more energetic than visible light. Depending on its wavelength, it can get through the ozone layer and affect our health in different ways. WebThe F-TiO2 photocatalyst was characterized using FE-SEM, HR-TEM, EDS, XPS, and UV-Vis, and the photocatalytic activity was evaluated by photodegradation of methylene blue under visible light. The results showed that doping with F reduced the energy band gap (3.04 eV) of TiO2, thereby increasing the photocatalytic activity in the visible-light region.
