The influence of auxiliary rare-earth element (REE) ions (M3+, M = Y, Gd, Tb) on the luminescence properties of the (EuxM1–x)2(BDC)3(H2O)4 (BDC2– = 1,4-benzenedicarboxylate) series was studied. The overall quantum yields (QYs) of the EuxM1–x series (M = Y, Gd; x > 0.05) appeared to be independent of both the ratio and the type of auxiliary metal ion. It is shown that M = Tb3+ does not cause luminescence enhancement.
