Radiation-chemical yield of excited neodymium(III) in laser liquids POCl3-MCln-(UO22+)-U-235-Nd3+ (M = Ti, Zr, Sn, or Sb)

摘要

Results of measurements of the yield of Nd3+ radioluminescence photons in inorganic laser liquids POCl3-MCln-(UO22+)-U-235-Nd3+ (M = Ti, Zr, Sn, or Sb) during homogeneous excitation by uranium alpha-particles are presented. It was found that the intensity of radioluminescence corresponding to the F-4(3/2) -> I-4(11/2) transition in neodymium ions depends on the solvent composition. Data on the radiation-chemical yield, G, of excited neodyneodymium ions in the POCl3-MCln-(UO22+)-U-235-Nd3+ (M = Ti, Zr, Sn, or Sb) system were obtained. At a neodymium concentration of 0.25 mol/l, the values of G for the excited ions were 0.60 +/- 0.10, 0.84 +/- 0.10, 1.20 +/- 0.10, and 1.64 +/- 0.16 ion/100 eV in solutions with TiCl4, ZrCl4, SnCl4, and SbCl5, respectively. The maximum yields of excited ions estimated at G = 1.68 +/- 0.10 and 2.20 +/- 0.24 ion/100 eV were obtained for the solutions with SnCl4 and SbG(5), respectively, at neodymium ion concentrations above 0.4 mol/l.
