“…Thus, in the case of the harpoon reaction a total transformation of the molecular structure is necessary in order to form exciplex molecule with an ionic bond. Therefore, the harpoon reaction should occur via an intermediate stage (8), which allows formation of the molecule with ionic bond [23]:…”

“…Moreover, many different UV radiation sources, emitting on transitions of exciplex molecules of inert gas halides, have been created. It should be noted that toxic mixtures, such as mixtures with mercury or cadmium vapor [7][8][9], are part of the working mixtures that have proved to be the best in practice. Therefore, despite a lot of existing gas mixtures being used to produce radiation of exciplex molecules, studies of working media on new non-traditional mixtures, in particular, on the xenon-rubidium bromide mixture, which have similar emission properties but contain only non-toxic and environmentally friendly species, are of interest.…”

The luminescence spectra of the longitudinal pulsed-periodic discharge in Xe–RbBr gas–vapour mixtures at low pressures are experimentally studied. Conditions for obtaining strong UV radiation of XeBr* exiplex molecules in the spectral range of 200–425 nm are found. The greatest output of the XeBr* UV radiation is provided at temperature of the gas-discharge tube walls of ~1000 K. The maximum UV emission power of the whole plasma volume is 4.8 W. Formation of XeBr* exciplex molecules in the pulsed-periodic discharge in Xe–RbBr gas–vapour mixtures at low pressures is discussed.

“…Excitation of working mixture was performed by generator of repetitively pulsed form of the output voltage with the possibility of frequency adjustment in the range of 1 -20 kHz and the amplitude of the voltage pulses in the range of 10 -30 kV. Diagnostics of spectral, temporal and energy characteristics of the radiation of gas-discharge plasma was carried out on the experimental setup description of which is presented in our articles [15] [17].…”

“…To date, several created and studied types of exciplex spontaneous sources of visible light in which to create gas-discharge plasma on working mixtures barrier discharge and other types of discharges have been used. In these works, for the most part, the main attention was focused on gas-discharge plasma on mixture of mercury dibromide vapor with gases: helium, neon, argon, xenon, krypton, nitrogen, and sulfur hexafluoride [9]- [17].…”

The results of diagnostics of spectral, temporal and energy characteristics of the radiation of gas-discharge plasma in a mixture of mercury diiodide vapor with helium in the spectral range of 350-900 nm, and the plasma parameters in the range of reduced electric field E/N = 1-100 Td are presented. The plasma is created in the barrier discharge device with a cylindrical aperture. The electrodes are placed 0.2 m in length at a distance of 0.015 m. The amplitude of the pump pulse, the duration and frequency were 20-30 kV, 150 ns and 1-20 kHz, respectively. Radiation in the visible region of the spectrum of mercury monoiodide exciplex molecule is revealed. Regularities in the optical characteristics of the plasma, depending on the partial pressures of the components of the mixture, the electron energy distribution function, mean electron energy, specific losses of discharge power on the process of dissociative excitation of mercury monoiodide (state 2 1 2 В + Σ) molecules as well as the rate constant of dissociative excitation of mercury monoiodide molecules in working mixture depending on the given reduced electric field are established.

“…These lamps are attractive due to their narrow-band short-wavelength emission suitable for intense illumination of large areas. In this paper, we study a mercurybromide dielectric-barrier-discharge (DBD) lamp related to excilamps [7][8][9][10][11][12]. The blue-green radiation of this lamp can find applications in scientific research, biotechnology, photonics, medicine, and can also be used to manufacture gasdischarge display panels [8].…”

In a nonequlibrium plasma of a gas-discharge HgBr lamp, the terminal electronic state of the HgBr(B-X) radiative transition with a peak wavelength of 502 nm remains populated for a relatively long time and is repeatedly excited to the B state in collisions with plasma electrons. This transfer of the HgBr molecules from the ground state X to the excited state B is the main mechanism of formation of the light-emitting molecules especially when the lamp is excited by double current pulses. According to our simulations, due to the electron-induced transitions between HgBr(X) and HgBr(B), the output characteristics of the DBD lamp operating in a double-pulse regime are better than those of the lamp operating in a single-pulse regime. In the considered case, the peak power is calculated to increase by a factor of about 2 and the lamp efficiency increases by about 50%.
