Abstract
The results of analysis of the spectral characteristics of short-wave radiation sources operating on transitions in argon, krypton, and xenon monohalogenides, as well as chlorine molecules, excited by a longitudinal low-pressure glow discharge are considered. Radiation emitted by ArCl*, KrCl*, XeCl*, Cl **2 , and Cl *2 molecules in a spectral range of 170–350 nm is optimized using complex working mixtures of Ar-Kr-(Xe)-Cl2 in the lamps. The average radiation power of the lamps ranges from 1 to 10 W for an efficiency of ≤25%. Optimization of wide-band lamps on transitions in chlorine molecules and the decay products of Freon-12 molecules (CF2Cl2) is carried out on mixtures of helium with chlorine and Freon-12 molecules. This makes it possible to develop lamps emitting in a spectral range of 140–270 nm and containing no costly inert gases (Xe or Kr) in their working mixtures. Exciplex halogen lamps with a wide-band emission spectrum in the VUV-UV range can be used in spectrometers as radiation sources in experiments with absorption and in high-energy chemistry, ecology, and medicine.
