摘要：

The environment of Eu3+ in zinc-thallium-tellurite glass of the molar composition 60TeO(2)-30TIO(05)-9.9ZnO-0.1Eu(2)O(3) was investigated by laser-induced fluorescence line narrowing (FLN) techniques using Eu3+ as a local site probe. From the site selective luminescence spectra of Eu3+ at 7 K, the energies of the Stark components of the F-7(1) and F-7(2) states were recorded and then the crystal field parameters B-nm were calculated assuming a C-2v site symmetry. The ratios B-22/B-20 and B-44/B-40 for each excitation energy within F-7(0)-D-5(0) transition were obtained and compared with the values calculated for Eu3+ in other types of glasses.
