Relaxation of charged and neutral particles in doped atomic solids: TSL, OSL, TSEE, OSEE and their interconnection

Abstract

Relaxation processes in nitrogen-containing Ar solids pre-irradiated by an electron beam are studied with the focus on the interconnection of relaxation channels in system of charged and neutral species. The results of correlated in real time measurements of thermally stimulated phenomena are presented. The experiments have been performed using activation spectroscopy methods – thermally stimulated exoelectron emission (TSEE), spectrally resolved thermally stimulated luminescence (TSL) measured in visible, NUV and VUV ranges. Solid evidence of the charge relaxation cascades triggering via radiative recombination of neutral species is presented.
