LUMINESCENT CHARACTERISTICS OF A PULSED DISCHARGE PLASMA IN Xe-KBr MIXTURE

Abstract

A mixture of xenon with a non-toxic halogen carrier Xe-KBr was used to create a plasma radiation source at the 282 nm transition of the XeBr* molecule excited by a high-voltage pulsed-periodic discharge. The luminescence spectra of the plasma of a longitudinal pulsed-periodic discharge in the Xe-KBr mixture at low pressures are experimentally studied. The most intensive UV bands of exciplex XeBr* molecules are recorded in the spectral range 250-350 nm. The spectral, temporal, and energetic characteristics of the radiation source are presented, as well as the dependence of the XeBr* exciplex molecule formation efficiency on the discharge excitation conditions. The optimal conditions for the excitation of the UV radiation in the pulsed-periodic discharge plasma are determined.
