On the Specific Quenching of Radioluminescence of Tb3+ Ions in Aqueous Solutions by Hydrogen Atom
Abstract
The influence of scavengers of the primary water radiolysis products \({\text{e}}_{{{\text{aq}}}}^{ - }\) and the H atom on the spectra and intensity of radioluminescence and photoluminescence of the Tb3+ ion in aqueous solutions of TbCl3 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 \({\text{e}}_{{{\text{aq}}}}^{ - }\) scavengers in the solution, with a similar effect of activation of Tb3+ radioluminescence being previously established for \({\text{e}}_{{{\text{aq}}}}^{ - }\) scavengers.
