Abstract
Results of measurements of the yield of Nd3+ radioluminescence photons in inorganic laser liquids POCl3-MCln-235UO 2+2 -Nd3+ (M = Ti, Zr, Sn, or Sb) during homogeneous excitation by uranium α-particles are presented. It was found that the intensity of radioluminescence corresponding to the 4 F 3/2 → 4 I 11/2 transition in neodymium ions depends on the solvent composition. Data on the radiation-chemical yield, G, of excited neodymium ions in the POCl3-MCln-235UO 2+2 -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 SbCl5, respectively, at neodymium ion concentrations above 0.4 mol/l.
