Abstract
In this paper the excitation spectra of the luminescence of the octahedral uranate group (UO6−6) are presented for various uranium‐doped compounds. The excitation bands have been assigned using the results of theoretical and experimental investigations into the spectroscopic properties of uranium hexafluoride which is isoelectronic with the octahedral uranate group. Charge transfer transitions from orbitals having mainly oxygen 2p character to orbitals having mainly uranium 5f charcter have been observed in the region 2.24–∼4 eV. Charge transfer transitions to orbitals having mainly uranium 6d character have been observed at 4.4 eV and at 5.4 eV.Keywords
