【摘要】 以稀土氧化物、硝酸铝和硼酸为原料,用高温球磨法制备红色荧光粉YAl₃（BO₃）₄:Eu³⁺,研究其结构、形貌和发光性能。结果表明,在700℃高温球磨制备YAl₃（BO₃）₄:Eu³⁺荧光粉,煅烧温度比硝酸盐分解法降低200℃,比高温固相法降低500℃;制备出的荧光粉粒度分布均匀,晶粒近似呈球状,尺寸为纳米级;在394 nm的紫外光激发下YAl₃（BO₃）₄:Eu³⁺荧光粉具有较好的发光性能,发射光以波长为618 nm的红光(Eu³⁺离子⁵D₀→⁷F₂跃迁)为主;Eu³⁺的最佳掺杂量为15%。更多还原

【Abstract】 The red phosphor yttrium aluminoborate doped with Eu³⁺ was prepared by high temperature ball milling method.The phosphor was characterized by X-ray diffraction（XRD）,scanning electron microscopy（SEM） and luminescence spectroscopy.The results show that Y³⁺ ions are replaced by Eu³⁺ ions in view of their similar sizes and valence state,the Eu³⁺ ions are non-centrosymmetric sites in YAl₃（BO₃）₄:Eu³⁺.The synthesis temperature of high temperature ball milling method is 700℃,which is obviously decreased in contrast to that of nitrate salts decomposition method（900℃） and conventional solid state reaction method（1200℃）.The particles are approximately nanometer-sized with narrow distribution range and spherical morphology.In the emission spectra under 394 nm excitation,the strongest peak at 618 nm is due to the forced electric dipole transition ⁵D₀→⁷F₂ of Eu³⁺ ions.更多还原
