Abstract

Absorption and luminescence spectra of Eu3+ ions in D2O and POCl3-SnCl4 inorganic solvents were measured. Oscillator strengths and spontaneous radiation transition probabilities for the most intense electron transitions in Eu3+ were calculated. Judd-Ofelt parameters, the radiative lifetime of the 5 D 0 metastable level of Eu3+ in D2O-Eu3+ and POCl3-SnCl4-Eu3+ solutions, and matrix elements for radiative transitions from the 5 D 0 level were determined. The luminescence lifetime of the 5 D 0 level of Eu3+ in these solutions was measured. The photoluminescence quantum yield for transitions from the 5 D 0 level of Eu3+ in 5 D 0 and POCl3-SnCl4-Eu3+ solutions was found to be 0.32 and 0.88, respectively.
