Another Route to the Ultraviolet

Dr. Zoran Falkenstein

Energetic ultraviolet radiation is useful in biological, physical and chemical applications such as the disinfection of drinking water and the photo-enhanced chemical vapor deposition of metallorganics and dielectric films.

These processes typically require the use of photons in the ultraviolet (λ <350 nm) or vacuum ultraviolet (λ <200 nm) spectral range. The radiation serves to excite or cleave chemical bonds and leads to the desired photoinduced reaction, mediated through radicals or other active chemical species…
