Digital Library of Periodicals of National Academy of Sciences of Ukraine| Summary: | Investigations of the optical characteristics of a gas-discharge plasma of an atmospheric pressure barrier
discharge on mixtures of zinc diiodide vapor with helium are presented. The repetition rate of the plasma pumping
pulses was 130 kHz. The regularities were established: in the emission spectra of a barrier discharge plasma in the
400…750 nm range with a resolution 0.05 nm, in the temporal characteristics of voltage and current, and the
radiation brightness dependences on the partial pressure of helium and nitrogen. The emission of exciplex ZnI*
molecules with a maximum of intensity at λ = 602 nm, excimer molecules I₂*, and lines of zinc and helium atoms
was revealed. The specific average radiation power in the spectral range Δλ = 550…650 nm was determinedwhich
and it is equal to 34 mW/cm³. |
