New data on the state of Tb3+ doping ions in the EuAl3(BO3)4 single crystals have been obtained by studying the electron paramagnetic resonance spectra within the X band and optical absorption spectra at 4 K in the visible range. Additionally, the specific heat of these crystals was measured and analyzed. It has been shown that the Tb3+ ions substitute the trivalent europium ones and lower crystal symmetry. In the crystal field, the ground multiplet of Tb3+ splits in such a way that two singlets located in close proximity are the lowest energy levels.
