摘要: Abstract An interesting daisy-like Y(OH)3:Eu microstructure was successfully prepared via a facile hydrothermal process employing potassium sodium tartrate (C4H4O6KNa) as structure-directing agent for the first time. Y2O3:Eu with same morphology obtained by calcining precursor at 800 °C 5 h. Phase and of products were investigated X-ray powder diffraction (XRD) scanning electron microscopy (SEM) respectively. It found that concentrations NaOH C4H4O6KNa played crucial roles in controlling particle size precursor. A possible formation mechanism novel proposed. The had stronger photoluminescence (PL) intensity than microrod reference nanoparticle.
