| Abstract: | ccording to Judd-Ofelt principle and ligand field theory, the allowing number ofelectric and magnetic dipole transition from the lowest excited state to the ground states(5D4-7Fj) for for f8 electron configuration in 32 point group are calculated and listed by usinggroup theory. Investigation of the high-resolution-emission spectra of the single crystalTbBenH4-H2O at 10K shows that the coordination symmetry of Tb3- in this complex isvery low. This result is consistent with the X-ray structure analysis. This set of calculated data would be available in studying the coordination symmetry of Tb3+ by determidetermination of fluorescence spectra. |
