説明

A lamp of extremely narrow inner diameter (usually narrower than 6mm) has been recently developed for liquid crystal display (LCD) backlighting and its importance is undoubtedly increasing. In this work, the Hg6p3P0,1,2 state densities, Hg+ ion density, electric field strength and electron temperature on the tube axis of Ar-Hg discharge lamp were measured under a varied Ar pressure. Ar+ ion and Ar2+ molecular ion in Ar discharge were detected with a quadrupole mass spectrometer as a function of Ar pressure. The variations of the Hg6p3P0,1,2 state densities and Hg+ ion ground state density are similar with varied Ar pressure. The formation of Hg+ ion with variation of Ar pressure at bath temperature 60℃ is the dominant ionization from the collision of the Hg6p3P0,1,2 metastable state atoms.
