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

Section: Plasmas and Gases
Original Author's Text: Ukrainian/English

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 feld, at which the specifc 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 efcient exciplex lamp with bands emitted in the blue-violet spectral
interval.

Key words: gas-discharge plasma, radiation emission by exciplex molecules, plasma parameters, mercury diiodide, xenon, neon.
