Abstract

The discharge of the gas mixture Kr-He-Xe was investigated as a source of vacuum ultraviolet for lighting purposes. The discharge characteristics of the Xe-He-Kr gas mixture were enhanced in comparison to those of Xe and a Xe-He gas mixture. The experimental results were evaluated by the infrared radiation from the positive column. The amount of infrared radiation under optimum conditions displayed higher efficiency than that of the He-Xe gas mixture, which results in the improved efficacy of lamp. This result was due to the emission properties that were improved by the potential energy transferred from the excited Kr to the Xe.
