| Abstract: | The first fluorescence lifetime studies in a trivalent rare earth-metal vapor complex NdCl3 · (AlCl3)χ are reported. The observed, temperature-dependent, nonradiative deactivation and the inferred radiative lifetime are discussed in terms of various models. At 803 K, corresponding to a density of 4.6 × 1017 Nd3+ ions/cm3 and a total system pressure ≈5 atm, the measured lifetime is 46 μs. |
