Abstract

Hydroxyapatite (HAP) was prepared by a hydrothermal synthesis method and also silver was introduced on the surface of HAP through an ion exchange reaction. The crystal phase and morphology of HAP were then evaluated by X-ray diffraction (XRD) and transmission electron microscopy (TEM). In addition, the absorption property of HAP was characterized by diffuse reflectance UV-Vis spectroscopy. The presence of silver nanoparticles on the surface of HAP was also verified by XRD and TEM analysis. Particularly, the silver doped HAP showed an enhanced absorption property in UV-Vis region compared to that of the pristine HAP.

본 연구에서는 수열합성법을 이용하여 수산화인회석을 합성하였다. 또한 이온 교환 반응을 통하여 수산화인회석 표면에 은을 도입하였다. 합성된 샘플의 결정성과 형태를 X-선 회절 분석과 투과전자현미경을 통하여 분석하였으며, 산란 반사 UV-vis 스펙트럼을 통하여 합성한 샘플의 광학적 특성을 조사하였다. 은이 도핑된 수산화인회석의 경우 은이 수산화인회석 표면에 나노입자 형태로 존재한다는 것을 X-선 회절 분석과 투과전자현미경 실험으로 확인하였다. 특히 수산화인회석과 비교하여 은 나노 입자가 도입된 수산화인회석의 경우에는 UV-Vis 영역에서 높은 흡광도를 나타내었다.
