Hydroxyapatite (HA) co-doped with La3+ and F− ions were synthesized by the precipitation method and sintered at 1,100°C for 1 hr. Samples were characterized by the standard experimental methods including the density, X-Ray Diffraction (XRD), Fourier Transform Infrared Spectroscopy (FTIR), and Scanning Electron Microscopy (SEM) to investigate their microstructure, phase formation, and bonding characteristics in detail. Moreover, the materials produced were identified using the microhardness tests. It was observed that in the most of materials, the hydroxyapatite was found to be the main phase with a minor amount of β-tricalcium phosphate (β-TCP). Furthermore, the presence of fluoride and small amount of β-TCP was verified with all the characteristic FTIR bands of hydroxyapatite for the majority of samples studied. The result in SEM evaluation is that the produced HA powders have less deformed, uniformly distributed, and regularly shaped particles. Here, the material density has changed towards a less dense state with the increasing rate of La doping, but statistically significant difference was not obtained (p, .1942 > .05) with increase of the F doping. A significant difference was obtained the microhardness values between La3+ and F− ions co-doped HA materials and pure HA (p [.0053] < .05). Accordingly, this study confirmed that since the La3+ and F− ions can potentially increase the efficacy of HA. According to the spectral, mechanical, and microstructure analysis result, this material can be as a good candidate product for use as an occluding material for dental application.

La3+ 和 F- 双掺杂多功能羟基磷灰石纳米粒子：合成和表征
羟基磷灰石 (HA) 与 La 3+和 F -共掺杂离子通过沉淀法合成并在 1,100°C 下烧结 1 小时。通过标准实验方法对样品进行表征，包括密度、X 射线衍射 (XRD)、傅里叶变换红外光谱 (FTIR) 和扫描电子显微镜 (SEM)，以详细研究其微观结构、相形成和键合特性。此外，生产的材料使用显微硬度测试进行鉴定。据观察，在大多数材料中，发现羟基磷灰石是主要相，少量β-磷酸三钙（β-TCP）。此外，对于大多数研究的样品，通过羟基磷灰石的所有特征 FTIR 波段验证了氟化物和少量 β-TCP 的存在。SEM评价的结果是所生产的HA粉末变形较小，均匀分布且形状规则的颗粒。在这里，材料密度随着 La 掺杂率的增加而向密度较低的状态变化，但没有获得统计学上的显着差异（p , .1942 > .05) 随着 F 掺杂的增加。La 3+和F -离子共掺杂HA材料与纯HA之间的显微硬度值存在显着差异（p [.0053] < .05）。因此，该研究证实，由于 La 3+和 F -离子可以潜在地提高 HA 的功效。根据光谱、力学和微观结构分析结果，该材料可以作为牙科应用的封堵材料的良好候选产品。
