Transition metal doped apatites as inert non-toxic pigments

This project focused on transition metal doped hydroxyapatite, namely copper doped Ca and Sr hydroxyapatite, which produces a bright colouration when synthesized. The intensity of the colouration increases with an increase in copper content as well. The objective was to investigate the structural an...
