摘要：
Absorption spectra of Tb3Ga5O12 and Tb-2(MoO4)(3) are measured in temperature range from 4.2 to 300 K. Two low-energy lines appear above 20 K. This lines are ascribed to the vibronic-assisted optical absorption. Energy of the zero-point vibrations should be taken into account when optical data are used in calculation of the crystal electric field parameters. (C) 2022 Elsevier B.V. All rights reserved.
