Background: Hydroxyapatite (HAp) is a remarkable member of the calcium phosphate family. It resembles natural bone in both structure and chemical composition. Owing to its bioactive and chemical properties, it has been used as a biocompatible osteogenesis and energy materials as discussed in patents.
Objective: To study the structural, optical properties and magnetic properties of hydroxyapatite and cobalt ions doped hydroxyapatite for biomedical application.
Method: Hydroxyapatite and cobalt ions doped hydroxyapatite were synthesized by ultrasonication assisted wet chemical synthesis.
Results: X-ray diffraction analysis confirmed the phase and crystallite size of hydroxyapatite. There was a 12% decrease in crystallite size compared to pristine. The functional groups and vibrational assignments of the samples were observed in infra-red and Raman spectra. Optical properties of the samples were analyzed by Diffuse Reflectance Spectroscopy, ultraviolet-visible and photoluminescence emission spectroscopy. Doped samples showed paramagnetic in nature.
Conclusion: Therefore, the cobalt doped samples could be employed in biomedical applications.
