Glow-discharge-pumped broadband ultraviolet lamp

Abstract

537.521The optical characteristics of a UV broadband lamp that was excited by a longitudinal glow discharge and operated on Kr-Br 2 -I 2 , Xe-Br 2 -I 2 , and Kr-Xe-Br 2 -I 2 mixtures are investigated. The interelectrode spacing in the lamp is 10 cm, the inner diameter of a discharge tube being 14 mm. The current-voltage characteristics, the emission spectra of the plasma, and the dependence of the intensity of spectral lines (the amplitude of radiation bands) on the power that was pumped into the plasma based on mixtures of various compositions and pressures, as well as the radiation power in the spectral range from 200 to 390 nm, are studied.

Emission characteristics of a gas-discharge plasma of water vapor in the vacuum UV region of the spectrum

“…(and also their decomposition products) with pumping by different types of gas discharges [1][2][3][4][5] have been increasingly widely used in microelectronics, photochemistry, environmental work, and medicine [6][7][8]. Efficient excimer emitters in the visible region have been developed for photobiology that are based on halides of Hg, Cd, Zn and pumped by barrier discharge [9,10].…”
