Study of Synthesis and Luminescent Characterization of the Coordinated Nano Terbium Oxide Colloids
Colloids of the coordinated terbium oxide are prepared by colloids precipitation method with ligands of acetylacetone (acac) and 2,2-bipyridine and pH regulating agent of NaOH solution. The fluorescent properties and structure of nanoparticles of the coordinated terbium oxide are characterized by fluorescence spectra, ultraviolet-visible spectra and high-resolution transmission electron microscopy (HRTEM). The results show that the nano terbium oxide particles coordinated by acac and 2,2′-bipy can radiate intense green light under ultraviolet irradiation, and their fluorescence spectrum presents typical characteristic emission peaks of Tb3+ ions. The HRTEM and selected area electron diffraction (SED) results show that the nanoparticles are terbium oxide with the size of 6 nm.
