摘要:
NaLa(WO4)(2):Eu microcrystals with shapes of four-arris shuttle, quadrangled star, and quadrangled dendrite were hydrothermally synthesized at 180 C for 16 h. The concentration of the reactants and cetyltrimethyl ammonium bromide (GAB) influenced the morphologies of the products. As La(NO3)(3), Na2WO4 and CTAB was 0.375, 1.0, and 1.0 mmol, respectively, four-arris shuttle was obtained. As the concentration of the reactants doubled and the amount of CTAB ranged from 0.4 to 2.0 mmol, quadrangled dendrite, quadrangled star and four-arris shuttle were prepared, respectively. Luminescence intensity measurement of the three morphologies of NaLa(WO4)(2):Eu showed that quadrangled dendrite was the strongest and four-arris shuttle was the lowest. (C) 2010 Elsevier Masson SAS.
