| Electron absorption and emission spectra of Eu3+ ion in stoichiometric KEu(WO4)2 were measured at the temperature range 15-300 K. The oscillator strengths of f-f transitions and the Judd-Ofelt parameters were evaluated. The assignment of vibronic transitions is given and mechanism of emission decay is discussed. |
