在室温下采用化学沉淀法制备了铽掺杂的羟基磷灰石(Tb-HAP),通过X射线衍射分析(XRD)、傅里叶变换红外光谱(FT-IR)和荧光光谱(PL)等对其结构和荧光性能进行了表征分析。XRD和FT-IR测试表明,Tb,3+,的掺杂对羟基磷灰石的结构没有显著影响。荧光光谱分析表明:在545 nm波长监测下,测得的最佳激发波长为378 nm。样品的发光强度随Tb,3+,在样品中的掺杂摩尔分数先增大后减小,在8%时发光最强。此外,Tb-HAP样品的荧光寿命随着Tb,3+,掺杂摩尔分数的增加呈现减小的趋势。
Hydroxyapatite particles doped with Tb,3+, (Tb-HAP) were prepared ,via, chemical deposition method. The crystalline phase, structural and fluorescent properties of the samples were investigated by X-ray diffraction (XRD), Fourier transform infarred (FT-IR) spectroscopy, and photoluminescence (PL) measurements, respectively. XRD and FT-IR results show that Tb,3+, doping has no significant influence on the structure of HAP. PL spectra of Tb-HAP samples show that the best excitation light is 378 nm when the wavelength of the monitoring light is 545 nm. The luminescent intensity of Tb-HAP sample reaches the maximum when the doping mole fraction of Tb,3+, is 8%. Furthermore, the fluorescent life of Tb-HAP samples present a decreasing trend along with the increasing of Tb,3+, concentration.
