Abstract: | The M-effect (monochromatization-effect) is a powerful tool which can give high intensity monochromatic spectra with a certain
wavelength depending on the type of used gas mixtures to generate plasma state. The effect consists in the emission of a single
spectral line of plasmas ignited in certain gas mixtures. The main condition to obtain the M effect is the presence of an
electropositive and an electronegative gas mixture. For example, in the case of Ne+H2 monochrome radiation was obtained, the wavelength of Ne being 585.3 nm (1s2–2p5). In this paper we prove the general character of this effect, i.e. if the optical emission spectra reduced to nearly one
line can be observed also in other gas mixture discharges, for example in the case of one electronegative gas and two electropositive
gases. Different other mixtures, as Xe+Ne+H2 and Xe+Ar+H2 have been studied. In all these cases, the M-effect appeared without doubt. |
