barrier discharge, gas-discharge plasma, radiation emission by exciplex molecules, plasma parameters, cadmium diiodide, heliumAbstract
The optical characteristics and plasma parameters have been found for the gas-discharge radiator emitting in the red spectral interval and operating on a mixture of cadmium diiodide vapor and helium. The reduced electric field strength at which the specific discharge power spent for the excitation of exciplex cadmium monoiodide molecules is maximal is determined as well. Additional processes of population of the upper B2Σ+1/2-state of exciplex cadmium monoiodide molecules giving rise to the radiation power growth have been revealed. The research results can be used to create a more efficient gas-discharge radiator emitting in the red spectral interval.
