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
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.
