Abstract

Results of measurements of the yield of radioluminescence photons from Nd3+ ions in POCl3-SnCl4-235UO 2+2 -Nd3+ and POCl3-ZrCl4-235UO 2+2 -Nd3+ solutions upon homogeneous excitation by uranium α-particles are presented. It was found that the radioluminescence intensity corresponding to the3 F 3/2 →4 I 11/2 transition of neodymium ions depends on the solvent composition. The radiation-chemical yield of excited Nd3+ ions is proportional to the neodymium concentration, being (1.50 ±0.05) and (0.23 ±0.02) excited ions per 100 eV in POCl3-SnCl4-235UO 2+2 -Nd3+ and POCl3-ZrCl4-235UO 2+2 -Nd3+ systems, respectively, at [Nd3+] = 0.4 mol/l.
