Low pressure (rare gas + water vapor)-discharge as a light source: electrical characteristics
Résumé
The strength of the electric field, electrode fall voltage, light emission and light efficiency of an (Ar + H2O) DC discharge as functions of water vapor content, argon pressure and electric current are presented. Obtained data make it possible to conclude that the light efficiency of the plasma under study can reach 30-40 Lum/Wt.
