TbAl3(BO3)4 should not be considered as a strictly stoichiometric compound. A variety of Tb1+xAl3−x(BO3)4 (x = −0.1–0.15) single phase compositions with the R32 space group were synthesized in the TbBO3–(Al2O3·B2O3) system. The K2Mo3O10–B2O3–Al2O3 flux was used to grow Tb1+xAl3−x(BO3)4 (x = 0.06 and 0.09) crystals. The orthoborates have typical luminescence in the green range which correlated with the 5D3 → 7F6 electron transition of Tb3+. However, deviating from stoichiometry can result in halving the quantum efficiency of luminescence. The SHG efficiency from 1064 nm radiation for Tb1+xAl3−x(BO3)4 crystals (x = 0.06 and 0.09) was found to be 1.82 and 1.53 times higher than that of KDP, respectively.
