Abstract
The optical absorption spectra and luminescence spectra of TbAl3(BO3)( 4) have been recorded. The crystal field transitions were assigned ass uming D-3 symmetry. The energy level diagram of the 4f(8) electronic c onfiguration of Tb3+ was parametrized in terms of 21 free-ion and 6 B- q(k) crystal-field parameters. A total number of 74 experimental cryst al-field levels was used in the fitting procedure. The crystal-field p arameters of Tb3+ in TbAl3(BO3)(4) are compared with those of Eu3+ in GdAl3(BO3)(4).
