Abstract

Eu(III)-trimesic acid (TMA) luminescent complex Nanorods were synthesized in the polyvinylpyrrolidone matrix. The obtained sample was characterized by elemental analysis, Inductively Coupled Plasma-atomic emission spectroscopy(ICP-AES), X-ray diffraction(XRD), Fourier-transform Infrared spectroscopy(FT-IR), transmission electron microscopy(TEM) and photoluminescence spectra (PL). The results demonstrated that its chemical constitution is PVP/Eu(MTA) • 2H₂O. The XRD patterns show that the complex was a new kind of crystal whose structure is totally different with the ligand. TEM image indicated that the complex is nanocrystal with rod shape in one dimension, the size of rod diameter is about 50~100 nm, and the length ranges from hundred nanometer to a few micrometers, in addition, the dispersity is better. Photoluminescence analysis indicated that the complex emits Eu ³⁺ characteristic luminescence under ultraviolet excitation. TG-DTA curves indicated that the complex is heat stable under the temperature of 454°C. Therefore an thermal decomposition mechanism is: Eu(MTA) • 2H₂O->Eu(MTA)-> Eu₂O₃.
