Plasma Conditions in a Moly-Oxide Electrodeless Bulb Discharge

Abstract

A mercury-free, molybdenum-oxide, electrode less discharge is describe with potential application to lighting. A spectrum is presented which displays emission in the near UV and throughout the visible region. Plasma diagnostics using spectroscopy and interferometry are presented to obtain the electron temperature and density. The Mo density is estimated from an actinometry approach including a collisional radiative model of the plasma. The low pressure metallic plasma is a non-equilibrium discharge with ~40 lumens per watt.
