Abstract

The quantum efficiency of fluorescence from the ⁵D₀ level of Eu³⁺ was obtained by two methods: by lifetime measurements and by comparison with a liquid standard. The quantum efficiency obtained by both methods was 0.95 ± 0.02. The probabilities of populating the ⁵D₀ level via excitation to the ⁵D₁, ⁵D₂, ⁵D₃, and ⁵L₆ levels have been calculated. The probability for the ⁵D₁ → ⁵D₀ transition of the excited Eu³⁺ in phosphate glasses has been calculated. The interaction of the electronic levels with the glass host is discussed.
