N2 - Proportional electroluminescence (EL) in noble gases is used in two-phase detectors for dark matter search to record (in the gas phase) the ionization signal induced by particle scattering in the liquid phase. The "standard" EL mechanism is considered to be due to noble gas excimer emission in the vacuum ultraviolet (VUV). In addition to it, there are two alternative mechanisms, producing light in the visible and near infrared (NIR) range. The first is due to bremsstrahlung of electrons scattered on neutral atoms (so-called neutral bremsstrahlung, NBrS). The second, responsible for electron avalanche scintillations in the NIR at higher electric fields, is due to transitions between excited atomic states.
