sacrificial template was designed to prepare monodisperse, pure bastnasite (RECO3F: RE = Ce, La, Pr, Nd) with a hole structure for the first time. A variety of morphologies, including jujube core-like, stacked nanoblocks, and stacked nanosheets were obtained through changing the ratio of reactants. The phase, structure, shapes, and photoluminescence properties of samples were characterized by X-ray diffraction
设计了使用RE(OH)CO 3胶体球作为牺牲模板的两步合成路线,以首次制备具有孔结构的单分散,纯硬脂石(R
ECO 3 F:RE = Ce,La,Pr,Nd) 。通过改变反应物的比例可以得到多种形态,包括枣核状,堆叠的纳米块和堆叠的纳米片。通过X射线衍射(XRD),场发射扫描电子显微镜(FE-
SEM),透射电子显微镜(
TEM)和光致发光(PL)光谱对样品的相,结构,形状和光致发光特性进行了表征。C
ECO 3 F:Ln 3+(Ln = Tb,Eu,Dy)
磷光体由于Ln 3+离子的f–f跃迁而分别发出绿色,黄色和蓝色发射。此外,详细描述了从Ce 3+到Dy 3+和Tb 3+的能量转移。
