Malinina A. Optical characteristics and parameters of gas-discharge plasma based on mixtures of mercury dibromide vapor with gases

The object of study - the processes of exciplex molecules excitation in a gas-discharge plasma on mercury dibromide vapor with gases mixtures, its goal - to establish the physical-chemical regularities that occur in gas-discharge exciplex radiation sources on multicomponent mixtures of mercury dibromide vapor with gases and ways to improve the efficiency of radiation in gas-discharge plasma in blue-green spectral range, research methods: optical, oscilloscope, the system of theoretical methods of analysis, synthesis, comparison and systematization; the modern equipment was used for experimental studies: the emission spectra, electrical and temporal characteristics of the gas-discharge plasma. For the first time physical-chemical regularities are established in the optical characteristics of gas-discharge plasma in mixtures of mercury dibromide vapor with gases: helium, krypton, xenon, nitrogen, and sulfur hexafluoride at pulse repetition rates 3 - 9 kHz, duration (0.2 - 0.7) ms; 10 Hz with pulse width 30 ns and 120 kHz sinusoidal voltage. Mechanism of increasing the radiation power in multicomponent mixtures is found. Efficiencies of elastic and inelastic collisions of electrons with work mixtures components have been defined, the design of the discharge cell with the help of which the efficiency of gas-discharge exciplex lamps is increased on 40% is proposed. Implementation is planned. Sphere of (industry) use: biotechnology and lighting companies and scientifically research organizations.
