[Synthesis and characterization of doping Terbium-dichlorosalicylic acid-N-Phenyl-beta-Naphthylamine complexes].

A solid complex of Terbium -DClSal (3,5-Dichlorosalicylic acid) NPhNAm(N-Phenyl-beta-Naphthylamine) was synthesized by co-precipitation in absolute ethanol solution at 60 degrees C. The complex was characterized by elemental analysis, IR absorption spectra, X-ray powder diffraction, and fluorescence spectrum. The result showed that it is crystal and its chemical composition is Tb(DClSal)3 (NPhNAm)2. Its emission peak locates at 543 nm, which is attributed to 5D4-->7F5 of Tb3+ ion.
