The effect of swift heavy oxygen ion irradiation of hydroxyapatite on its in vitro bioactivity was studied. The irradiation experiment was performed using oxygen ions at energy of 100 MeV with 1 x 10(12) and 1 x 10(13) ions/cm2 fluence range. The irradiated samples were characterized by glancing angle X-ray diffraction (GXRD), photoluminescence spectroscopy (PL) and scanning electron microscopy (SEM). GXRD showed that irradiated samples exhibited better crystallinity. The irradiated samples revealed an increase in PL intensity. In addition, the irradiated hydroxyapatite was found to have enhanced bioactivity.
研究了 swift 重氧离子辐照羟基磷灰石对其体外生物活性的影响。辐照实验使用能量为 100 MeV 的氧离子，辐照剂量分别为 1×10(12)和 1×10(13)ions/cm2。通过掠角 X 射线衍射（GXRD）、光致发光光谱（PL）和扫描电子显微镜（SEM）对辐照后的样品进行了表征。GXRD 表明辐照后的样品表现出更好的结晶度。PL 强度的增加表明辐照后的样品具有更高的发光强度。此外，还发现辐照羟基磷灰石具有增强的生物活性。
