Abstract

Intrinsic ionic centers in solid Xe were produced by (i) ionization in situ by vacuum ultraviolet (VUV) light and (ii) deposition of ion-containing gas on cooled substrate. Laser-induced fluorescence (LIF) from the samples was studied in the range of transitions between the ground state of ionic centers and the lower excited states related to the ²P_1/2, ²P_3/2 limits of Xe ions. The influence of the lattice defects which act as traps for charge carriers was examined and conditions of the stability of ionic centers were discussed. The coincidence of the LIF band observed with the samples grown from discharge with that observed under band-to-band excitation was found. It suggests that the electronic structure of self-trapped holes (STHs) is identical with that of intrinsic ionic centers formed in solid Xe after deposition of ion-containing gas (Xe₂⁺).
