An excimer laser, sometimes more correctly called an exciplex laser, is a form of ultraviolet laser which is commonly used in the production of microelectronic devices, semiconductor based integrated circuits or "chips", eye surgery, and micromachining. In this paper, we report the growth of thin tantalum pentoxide films on Si (100) and quartz by photo-induced chemical vapour deposition (photo-CVD) using a 222 nm excimer lamp. Feb 13, 2018 · In their earlier studies, Brenner’s team demonstrated that far-UVC light generated by filtered excimer lamps emitting in the 207–222 nm wavelength range, was effective at killing MRSA (methicillin-resistant S. aureus) bacteria, a common cause of surgical wound infections but not harm human or mouse skin.

Quark's excimer lamp VUV enables your new applications without wet cleaning process.Quark pursues further developments in application fields of our vacuum ultraviolet excimer lamps in semiconductor, biotechnology, environmental science, and polymer processing for a future.
Dec 23, 2005 · After irradiation with the 222 nm excimer lamp the ratios were different. Without photoreactivation, an irradiation of 106 J/m 2 at 222 nm was sufficient for a 4 log reduction for E. coli and 88 J/m 2 for Y. enterolytica. With photoreactivation 161 J/m 2 were necessary for E. coli to get a 4 log reduction and 117 J/m 2 for Y. enterolytica. и Phosphors are used to transform the UV radiation into @[email protected] radiation. This is the basis of mercury-free fluorescent lamps and of flat plasma-display panels with a large screen.
UV Lamps. We used an excimer lamp based on a krypton-chlorine (Kr-Cl) gas mixture that emits principally at 222 nm. The lamp (High Current Electronics Institute, Tomsk, Russia) was air cooled with a 6,000-mm 2 exit window (). и and 222 nm [32]. Excimer lamps are small, rugged, inexpensive, sufficiently intense, and long-lived (10,000 to 100,000 h) [32–34]; several studies [35–38] have been published on the bactericidal properties of far-UVC excimer lamps, but the suggestion that,200 nm wavelength UV is differentially cytotoxic to bacteria relative to human cells ...
