Abstract

Electrodeless discharge lamps (EDL) containing different sulfur compounds (elemental sulfur, H₂S, SO₂, ZnS, Na₂S, and CS₂) have been fabricated using quartz tubes (30 mm long by 8 mm i.d.) and He, Ar, Ne, Kr, or Xe as fill gases. Intensity and stability of EDL have been observed using fill-gas pressures ranging from 0.01 to 1.7 Torr at 216.9, 469.5, 545.4 (sulfur lines) and 384.0 nm (S₂ band head). Data are presented showing the effects of temperature on the intensity and stability of the EDL. Optimal conditions for each sulfur compound and fill gas are given.
