  • Abstract
    The gas-phase emitter effect of dysprosium is demonstrated by high-speed photography, spectroscopic, and pyrometric measurements at a high-pressure mercury lamp doped with Nal/Tll/Dyl3, which is operated in a transparent yttrium-aluminia-garnet tube with an f = 100 Hz switched dc current.
