Abstract
Optical absorption spectra of YbAl3(BO3)4, TmAl3(BO3)4 and TbFe3(BO 3)4 trigonal crystals have been studied in temperature range 2-300 K. Temperature behavior of absorption lines parameters has shown, that during some f-f transitions the local environment of rare earth ions undergo distortions, which are absent in the ground state.
