Abstract
High-resolution (< 1 Aå) VUV emission and excitation spectra as well as luminescence decay kinetics have been studied for several fluoride crystals containing Gd3+ and Lu3+ ions under excitation by synchrotron radiation. The obtained results evidently show that VUV luminescence (~ 10 eV) observed from these crystals originates from 5d-4f transitions in the Gd3+ and Lu3+ ions. Only fast spin-allowed 5d-4f luminescence is observed from Gd compounds, whereas both spin-forbidden and spin-allowed 5d-4f luminescence has been detected from Lu compounds, the latter being observed only at high enough (T > 100 K) temperatures.
