  水热法获得的 Na3RE(PO4)2 磷酸盐的特性，其中 RE = La、Ce、Nd、Gd 或 Er

  摘要：

  Na 3 RE (PO 4 ) 2磷酸盐（其中RE：La、Ce、Nd、Gd或Er）是通过在温和的水热条件下从溶胶中沉淀获得的。通过XRD、SEM、ICP/OES和DSC/TG方法对粉末进行表征。所得沉淀物中Na: RE :P的摩尔比为3:1:2，证明成功合成了Na 3 RE (PO 4 ) 2化合物。粉末由不结块的纺锤形或花状颗粒组成，大小可达 5 微米。大多数得到的粉末具有三角结构，这是 Na 的高温多晶型物的特征3重(PO 4 ) 2。一个例外是 Na 3 La(PO 4 ) 2化合物，它以未知类型的结构结晶。在加热下，Na 3 RE (PO 4 ) 2磷酸盐会改变它们的结构。它们的多晶型转变路径，即转变温度及其结构变化，取决于RE 3+半径大小。对于在高温下加热的 La、Ce 和 Nd 化合物，仅观察到斜方晶型多晶型，而 Na 3 Er(PO 4 ) 2的单斜晶型或斜方晶型多晶型Na

  phosphors used in ultraviolet (UV) based white light-emitting diodes (WLEDs), a novel red Na3.6Y1.8(PO4)3:Eu3+ (NYP:Eu3+) phosphor was successfully prepared by a solid-state method. Rietveld refinement analysis determined that NYP has a cubic unit cell with space group Pm-3m. The structural properties were analyzed in detail by employing X-ray diffraction (XRD), transmission electron microscopy (TEM)

  摘要 为了开发用于紫外 (UV) 基白光发光二极管 (WLED) 的潜在荧光粉，通过固态方法成功制备了一种新型红色 Na3.6Y1.8(PO4)3:Eu3+ (NYP:Eu3+) 荧光粉。 . Rietveld 细化分析确定 NYP 具有空间群为 Pm-3m 的立方晶胞。采用X射线衍射(XRD)、透射电子显微镜(TEM)和能谱仪对结构特性进行了详细分析。扫描电子显微镜 (SEM) 图像揭示了 NYP:Eu3+ 颗粒的不规则形态，元素映射证实 Eu3+ 离子均匀分布在 Y3+ 位点上。光致发光 (PL) 光谱在 394 nm 激发下表现出强烈的红色发射，NYP 主体中的最佳 Eu3+ 掺杂浓度确定为 30 mol%。计算出的临界距离约为 13.954 A，偶极-偶极相互作用是浓度猝灭机制的原因。NYP:Eu3+ 荧光粉表现出高热稳定性，在 424 K 时的发射强度是 298 K 时的 97.4%。此外，通过采用红色、绿色

  The Na3Y(PO4)(2) phosphate has been obtained by hydrothermal route and characterized by powder XRD, differential scanning calorimetry/thermogravimetric analysis (DSC/TGA), SEM and FTIR spectroscopy. The effect of synthesis conditions as well as the addition of complexing agents and surfactants on phase purity and microstructure of synthesized powders has been studied. The powders obtained by the hydrothermal technique exhibit uniform spindle-shape. The Na3Y(PO4)(2) compound shows three polymorphic transitions and can be crystallized in trigonal, monoclinic and/or orthorhombic structure. (C) 2014 Elsevier B.V. All rights reserved.

  Na3RE(PO4)(2) orthophosphates, where RE = Y and Gd, doped with Yb3+ ions were synthesised by hydrothermal method and characterised by X-ray diffraction, microscopic, IR and Raman techniques. The emission, excitation spectra were recorded at room temperature and fluorescence decay time was determined. As-synthesised samples crystallise in a trigonal modification and during calcination at 500 degrees C they transform to a monoclinic or orthorhombic symmetry (for yttrium and gadolinium compounds, respectively). Finally, the samples calcined at 700 degrees C do not reveal the trigonal symmetry. The morphology of particles for all samples is similar and resembles rice grains. All the obtained for the studied orthophosphates data were compared to those previously reported for the same compounds synthesised by Pechini method. (C) 2015 Elsevier B.V. All rights reserved.

  The phase diagram of the system YPO4-Na3PO4 has been determined by differential, X-ray and microscopic methods. The system contains two intermediate compounds, Na3Y(PO4)2 and Na3Y2(PO4)3. These double orthophosphates melt congruently at 1515 and 1635-degrees-C, respectively. Compound Na3Y(PO4)2 shows a polymorphic transition at 850-degrees-C and Na3Y2(PO4)3 shows one at 470-degrees-C.
