Importance of a role of (EuN3)2+ complex generated in the Eu3+/N3-/H2O2 system studied by the chemiluminescent method

Importance of a role of (EuN3)2+ complex generated in the Eu3+/N3-/H2O2 system studied by the chemiluminescent method

Chemiluminescence has been studied in the systems containing hydrogen peroxide H2O2 and Eu3+ and N3- ions. Ultraweak emission lasting for a few tens of hours has been observed. The dominant bands in the spectral distribution of the chemiluminescence are those of λ=594 and 620 nm,which proves that ex...
