In this research area, we investigate the optical and electrical properties of vacancy-type defects in hydroxyapatite (HAp), both undoped and doped with magnetic impurities. We utilize advanced electron microscopy techniques, such as cathodoluminescence, to evaluate the luminescent properties of these HAp nanostructures. Additionally, we employ photoluminescence and paramagnetic electron resonance techniques to characterize and correlate point defects.
To further understand the physical chemistry properties of HAp, we use X-ray photoelectron spectroscopy. Our research also includes assessing the biocompatibility of HAp to fabricate osteoinductive scaffolds and materials suitable for use as contrast agents in nuclear magnetic resonance imaging during bone regeneration treatments.
