In the last 20 years, studies performed in electronegative-electropositive gas mixtures
plasma, at a total pressure varying in the range of ten to hundred mbar, reported the
appearance of a quasi-mochromatization effect of the emitted radiation. Due to the fact that
the modified spectrum is reduced to this dominant line, the phenomenon was called the
“Monochromatisation-effect”(M-effect). For instance, in Ne+ H2 gas mixtures plasma in a

In the last 20 years, studies performed in electronegative-electropositive gas mixtures plasma, at a total pressure varying in the range of ten to hundred mbar, reported the appearance of a quasi-mochromatization effect of the emitted radiation. Due to the fact that the modified spectrum is reduced to this dominant line, the phenomenon was called the “Monochromatisation-effect”(M-effect).
For instance, in Ne+ H2 gas mixtures plasma in a dielectric barrier discharge (DBD), the M-effect consists in the reduction of the discharge emission spectrum practice at one strong spectral line λ= 585.3 nm [1÷ 4]. Figures 1 show the emission spectrum of a dielectric barrier discharge in Ne+ H2 gas mixtures.
