Abstract: | Chemiluminescence has been observed in the reduction of perchloric aqueous solutions of XeO3 with Eu2+ ions, Fast (several seconds) consumption of EuII occurs when the ratio of the initial concentrations of the reactants (Eu2+]0 : XeO3]0 < 6; however, the chemiluminescence remains sufficiently bright and prolonged (up to –10 min after nearly complete oxidation of EuII to EuIII). The assumption was made that intermediates in the reduction of XeO3 participate in the chemiluminescent stages of the process.Translated fromIzvestiya Akademii Nauk.
