Radiochemistry Aims and scope

Abstract

Lifetime of the Nd3+ luminescence in POCl3-TiCl4-235UO 2+2 -Nd3+ solutions is almost independent of the concentrations of neodymium and uranyl ions; it attains the maximal value of 220 μs at [TiCl4] = 0.20−0.35 M and increases with increasing synthesis time, reaching 220 μs at t = 40−60 min. Upon storage, the Nd3+ luminescence lifetime decreases by 20–30% in 2 months, and in 2 years it decreases to 60–80 μs in all the samples. Simultaneously with decreasing Nd3+ luminescence lifetime, multiple increase in the intensity of the absorption bands of the OH groups is observed in the near-IR range of the absorption spectra of POCl3-TiCl4-235UO 2+2 -Nd3+ solutions.
