The Luminous and Magnetic Properties of Tb<SUP>3+</SUP>-Doped Four Angle Star-Like NaGd(WO<SUB>4</SUB>)<SUB>2</SUB>

Abstract

Four angle star-like double tungstates NaGd(WO4)2 have been prepared hydrothermally with cetyl trimethyl ammonium bromide (CTAB) as the chelating agent and ethanol as the mixing solvent. Monodisperse micron-sized four angle star-like NaGd(WO4)2 were fabricated for the first time. The samples were characterized by powder X-ray diffraction (XRD), scanning electron microscopy (SEM), Fourier transform infrared spectroscopy (FT-IR), and vibrating sample magnetrometer (VSM) techniques. This work emphasizes the luminescence properties of Tb(3+)-doped NaGd(WO4)2 under ultraviolet (UV) and vacuum ultraviolet (VUV) excitation and the magnetic properties. The results demonstrate the phosphors are expected to have potential applications in weak lighting systems and magnetic resonance imaging.
