Characteristics of Discharge Spectra in Microwave-Induced Electrodeless Sulfur Lamp

摘要

We confirmed the transition of the spectrum from UV to visible, evidently because of S_2 molecules at high pressure. We also observed UV and IR lines of the buffer gas, and sulfur atomic line emission for a few seconds after initiation, and the disappearance of the sulfur deposit on the wall after 15 seconds.
