Investigation of luminescence in the 420 nm range as a result of photolysis of KrF2 in mixtures with Ar, Kr, and N2

An investigation was made of the brightness of Kr₂F* luminescence (λ = 420 ± 45 nm) in KrF₂–CF₄–N₂ (Ar, Kr) mixtures at a total pressure of 2 atm, excited by radiation from an open high-current discharge, as a function of the N₂ and Kr concentration. Measurements were made of the rate constants of the following reactions: KrF* + Kr + M→ Kr₂F* + M(He, CF₄, Kr), kτ = 5.8 × 10^–39 cm⁶, KrF* + N₂ + M → KrN₂F* + M(He, CF₄, N₂), kτ = 1.3 × 10^–39 cm⁶.
