  • Publication number: 20170072628
    Abstract: One aspect of the invention provides a method of generating ultraviolet radiation. The method includes: introducing a mixture of nitrogen gas and helium gas into a dielectric barrier discharge device including a high voltage electrode and a ground electrode separated by a gap and a dielectric; and applying suitable electricity to the high voltage electrode, thereby generating ultraviolet radiation. Another aspect of the invention provides a plasma- and ultraviolet-generating nozzle including: a dielectric barrier discharge device; and a controller programmed to control flows of gas into the dielectric barrier discharge device and application of suitable electricity to the dielectric barrier discharge device to selectively generate either plasma or ultraviolet radiation. Another aspect of the invention provides a printing system including: a motion control system; and the plasma- and ultraviolet-generating nozzle as described herein coupled to the motion control system.
