Salicylaldehyde salicylhydrazone (C_14H_12N_2O_3, H_3L) and its thirteen new complexes with rare earth have been synthesized. The formula of the complexes is K[RE(HL)_2]·nH_2O (RE = La, Pr, Nd, Sm, Eu, Gd, Tb, Dy, Er, Tm, Yb, Lu, Y; HL is the dinegative ion of Salicylaldehyde salicylhydrazone), which can be confirmed by elemental analysis, chemical analysis and molar conductance. The bond formation of the complexes was characterized by IR, ~1H NMR and UV, and the relationship of the emission wavelength with the atomic number and ion force, which coincided with some law was characterized by fluorescence. The bioactivity test shows the different bacteriostasis effects of the complexes against Phytophthora capsic, Fusarium oxysporium f. sp and vasinfoltum, Altemaaria altemaea.
