Impact of n,γ-irradiation on organic complexes of rare earth metals.

ABSTRACT: The complexes of La, Ce, Nd, Sm, Eu, Tb and Yb with benzoxazolyl-phenolate, benzothiazolyl-phenolate, benzoxazolyl-naphtholate, benzothiazolyl-naphtholate and 4,4,4-trifluoro-1-(2-thienyl)-1,3-butanedione ligands were treated with n,γ-irradiation upon a sustained (45 h, absorbed dose of 120 krad, flux of neutrons 5·10¹³ n/cm²) and a pulse mode (3 ms, absorbed dose of 130 krad, flux of neutrons 3.6·10¹³ n/cm²). It was found that main characteristics of the compounds (shape of substance, color, IR absorption and photoluminescent spectra) have not changed. With an example of cerium complex [Ce(OON)₃]₂ it was revealed that the molecular structure of compounds after strong pulse irradiation also does not changed. However, compute
