Abstract

Luminescence of the glass of mole composition 50 InF₃:20 PbF₂:25 BaF₂:5 SrF₂:5 YF₃:2 AlF₃:0.1 UO₂F₂ has an almost exponential decay with lifetime 0.63 ms and is due to uranyl groups. Comparison of the absorption and excitation spectra allow detection of a significant concentration of uranium (IV), and perhaps also of U(V). Uranium in these lower oxidation states does not quench the uranyl luminescence extensively, and the observed lifetime is the longest observed in any vitreous material.
