摘要：
The influence of scavengers of the primary water radiolysis products e(-)aq and the H atom on the spectra and intensity of radioluminescence and photoluminescence of the Tb3+ ion in aqueous solutions of TbCl(3 )and Tb(NO3)(3) is considered. The effect of activation of Tb3+ radioluminescence in the presence of H scavengers has been revealed, indicating the presence of a specific (Tb3+)* quenching reaction by this radiolysis product, which is inhibited by its scavengers. Enhancement in the activation has been revealed in the joint presence of H and e(-)aq scavengers in the solution, with a similar effect of activation of Tb3+ radioluminescence being previously established for e(-)aq scavengers.
