摘要：

The lifetime of luminescence in NaCl:Yb2+ crystals has been investigated using a streak-camera method. Two emission bands peaking at 400 and 432 nm (called bands I and II, respectively) are observed. In addition to a long lifetime of more than 0.3 ms previously observed for band II, it was observed that band I has a short lifetime of less than 3 mus and the lifetime decreases with increasing temperature, reaching a short lifetime of 15 ns at 290 K. A kinetic analysis of the lifetimes and intensities of the bands in terms of three rate constants was made. The temperature dependence of the nonradiative rate constant was shown to be well reproduced by multiple-phonon-decay formulas.
