title: Synthesis and characterization of nano-PVP/EuL3 luminescent complex.
abstract: Nano-sized rare earth europium [Eu(III)]-benzoic acid [HL] luminescent complex powders have been synthesized in polyvinylpyrrolidone matrix by precipitation method. The chemical constitution of the complex has been demonstrated as PVP/EuL3 by a combination of elemental analysis, inductively coupled plasma-atomic emission spectroscopy (ICP-AES) and fourier-transform infrared spectroscopy (FT-IR). X-ray diffraction analysis (XRD) and scanning electron microscopy (SEM) have shown that the complex is a new nanocrystal whose structure is totally different from the ligand. Thermogravimetric/Differential thermal analysis (TG/DTA) have indicated that the luminescent complex is thermally stable below 500 degrees C. Photoluminescence spectra (PL) have shown that the nanocomplex can emit Eu3+ characteristic red fluorescence under ultraviolet excitation.
