Mechanism of Growth of the Intensity of Radiation Emitted in the Blue-Violet Spectral Interval by Gas-Discharge Plasma Generated in the Mixtures of Mercury Diiodide Vapor, Xenon, and Neon

Abstract

A mechanism allowing the intensity of radiation emitted in the blue-violet spectral interval by gas-discharge plasma created in the mixtures of mercury diiodide vapor, xenon, and neon to be increased in comparison with the intensity of radiation from gas-discharge plasma in the mixtures of mercury diiodide vapor and neon is established. The plasma parameters and the reduced electric field, at which the specific discharge power spent for the excitation of mercury monoiodide exciplex molecules is maximum, are determined. The research results can be used for the creation of a more efficient exciplex lamp with bands emitted in the blue-violet spectral interval. K e y w o r d s: gas-discharge plasma, radiation emission by exciplex molecules, plasma parameters, mercury diiodide, xenon, neon.

Investigation of the conditions of synthesis of metal and chalcopyrite films from the degradation products of electrodes of an overstressed nanosecond discharge in argon and air

“…The characteristic spectral line of the nitrogen ion with a wavelength λ = 500.5 nm N II, which is observed in the emission spectra of nanosecond discharges in air, also appeared in the plasma radiation spectrum [28]. The characteristic spectral lines of the copper atom in the visible range of the spectrum 510.55; 515.83; 521.04; 556.69 nm Cu I had low-intensity, in contrast to the case of overstressed nanosecond discharge plasma between copper electrodes in nitrogen or air, when there was an effective process of energy transfer from nitrogen molecules in metastable states to copper atoms [29,30]. In the red region of the spectrum, the 618.86 nm spectral line of Cu II was distinguished by its intensity.…”
