Luminescence Characteristics of a Low-Temperature Plasma Based on a Helium-Glutamine Mixture

摘要

Theluminescence spectra of a low-temperature plasma of a pulse-periodic discharge in a He-Glu mixture at low pressures not exceeding several tens of Torr have been experimentally studied for the first time. In the spectral range of 200-850 nm, there are intense UVb ands of the obtained fragments of glutamine mol- ecules, namely, nitrogen molecules N-2* (C-3 Pi(u) -> B-3 Pi(g)), and emission bands of carbon monoxides CO* (B-1 Sigma -> A(1)Pi) in the visible and infrared regions. The highest luminescence yield of molecules of glutamine fragments is achieved at a temperature of the gas-discharge tube wall not exceeding 140 degrees C.
