## Description

- description: Coprecipitation with rare-earth nitrate, ammonium sulfate and ammonium
    hydroxide produced hydroxide-type amorphous precursors incorporating sulfate and
    carbonate anions, from which [(Gd1-xLax)0.99Tb0.01]2O2SO4 and [(Gd1-xLax)0.99Tb0.01]2O2S
    were obtained as two series of nanophosphors by calcination at 950°C in air and
    hydrogen, respectively. The detailed characterization by XRD, SEM/TEM, BET and
    particle sizing confirmed that solid solutions were directly formed and that the
    products have small crystallite size, unimodal size distribution and high specific
    surface area, revealing the advantages of the synthesis method. Photoluminescence
    study revealed that La3+ admixture may significantly improve the 545 nm main emission
    of Tb3+ for both the phosphor series. Furthermore, the 545 nm main emission of
    [(Gd1-xLax)0.99Tb0.01]2O2SO4 was identified to have an excellent thermal stability,
    which retained over 90% of its room temperature intensity at 150°C (no quenching
    for Gd2O2SO4:Tb3+). The two series of phosphors were comparatively studied for
    their excitation and luminescence performances, as a function of temperature and
    La3+ content, and the results were rationalized by considering bandgap, crystal
    structure, UV absorption, and the character of chemical bonds.
