Abstract
This paper reports a novel way for the synthesis of erbium (Er) doped hydroxyapatite (HA) nanostructure to achieve strong and stable near-infrared light emission at ∼1540nm of hydroxyapatite, particularly, by applying an optimum annealing temperature. The Er doped HA was observed to have a nanowire structure. As annealed 600°C specimens, the XRD diffraction peaks were to be hydroxyapatite; however a mixture of hydroxyapatite and β-tricalcium phosphate phase (β-TCP) when annealed temperatures of 800–1200°C were used. The formation of HA/β-TCP of the Er doped HA specimens resulted in a significantly enhanced light emission at ∼1540nm, which was potential application in waveguide telecommunication and biomedicine.
