ResumoThe temperature dependence of the lifetime of ${\mathrm{Cu}}^{+}$ impurity ions in single-crystal sodium fluoride has been analyzed. In order to describe the emission process occurring in this system, we have proposed a three-level model including the ground state and two close excited states in thermal equilibrium. Information is deduced concerning mainly their emission probabilities and their energy differences. A calculation of the mixing of these triplet emitting levels with other excited states is in very good agreement with our experimental results.
