Emitting characteristics and parameters of gas-discharge plasma on a mixture of mercury dichloride vapor with nitrogen

Abstract

The article presents the results of the studies of optical characteristics and parameters of a gas-discharge barrier-discharge plasma on a mixture of mercury dichloride vapor with nitrogen, which was the working medium of an exciplex gas-discharge emitter. The purpose of the study was to identify the regularities in the optical characteristics of a gas-discharge plasma on a mixture of mercury dichloride vapor with nitrogen; to determine the partial pressure of a bu(cid:27)er gas nitrogen at which the maximum radiation power in the blue-green spectral range in the emitters is reached; to determine the plasma parameters depending on the value of the reduced electric (cid:28)eld ( E/N is the ratio of the electric (cid:28)eld strength to the total concentration of the components of the working mixture) and also establish their values for the E/N value at which the maximum radiation power was observed in the experiment. The working mixture in the atmospheric-pressure barrier discharge was excited by a
