摘要：

Absorption and fluorescence measurements have been performed on pure Eu2Te4O11 tellurium oxide and on Eu3+-doped Gd2Te4O11 samples. The spectra were recorded at liquid helium, liquid nitrogen and room temperatures. In this monoclinic host matrix, the rare earth occupies a single crystallographic point site, with the very low symmetry C1. The energy level scheme is derived, from the experimental data, for the F-7(J)(J = 0,1,2,3,4) ground multiplet of the 4f6 configuration of Eu3+. Despite the low symmetry for the rare earth, parametrization of the crystal field effects was carried out with very good r.m.s. standard deviations and residues.
