Abstract Sm3+-doped β-dicalcium silicate (β-Ca2SiO4: Sm3+) was resoundingly prepared by the traditional high-temperature solid-state reaction method. The crystal structure, morphology and composition of β-Ca2SiO4: Sm3+ before and after mineralization was characterized by X-ray diffractometer (XRD), fourier transform infrared spectroscopy (FTIR), scanning electron microscopy (SEM), energy dispersive X-ray spectroscopy (EDS), respectively. The luminescence properties of β-Ca2SiO4: Sm3+ before and after mineralization were investigated by luminescence spectroscopy. The results show that Sm3+ ion has the effect of stabilizing β-Ca2SiO4 and β-Ca2SiO4: Sm3+ has good biological activity and can be converted to hydroxyapatite (HA) in simulated body fluid. Meanwhile, with the prolongation of mineralization time, the luminescence intensity of Sm3+ ion decreased gradually, and the CIE chromaticity coordinates moved from orange region to yellow green region. This suggests that the evolution of luminescence properties can be used as an obvious qualitative feature to monitor the mineralization process of β-Ca2SiO4: Sm3+.

在 Sm3+ 掺杂的 β-硅酸二钙矿化过程中通过发光强度和颜色监测羟基磷灰石转化

摘要 Sm3+掺杂β-硅酸二钙(β-Ca2SiO4:Sm3+)是采用传统的高温固相反应法制备的。采用X射线衍射仪（XRD）、傅里叶变换红外光谱（FTIR）、扫描电子显微镜（SEM）、能量色散X射线光谱仪对β-Ca2SiO4：Sm3+矿化前后的晶体结构、形貌和组成进行表征（ EDS），分别。通过发光光谱研究了β-Ca2SiO4:Sm3+矿化前后的发光特性。结果表明，Sm3+离子具有稳定β-Ca2SiO4和β-Ca2SiO4的作用：Sm3+具有良好的生物活性，可在模拟体液中转化为羟基磷灰石（HA）。同时，随着成矿时间的延长，Sm3+离子的发光强度逐渐降低，CIE色度坐标由橙色区域向黄绿色区域移动。这表明发光特性的演变可以作为一个明显的定性特征来监测 β-Ca2SiO4: Sm3+ 的矿化过程。
