Abstract

The resonant vibronic effect in high-resolution luminescence spectra of europium compounds is investigated. The cases of weak and strong nonadiabatic vibronic mixing between the ⁷F₂-electronic state of Eu³⁺ and near-resonant vibronic satellites of the ⁷F₀-electronic state are considered. The intensity redistribution and line shifts in the region of the e⁵D₀-⁷F₂ transition are observed. The conditions of resonance disappear in the deuterated compounds when vibration frequencies are appreciably decreased. Creation of new vibronic states is witnessed by emergence of their satellites due to lattice vibrations in vibronic sideband of ⁵D₀-⁷F₂ transition.
