the present work addresses the study of the structural and photoluminscent
properties of hydroxyapatite (HA) and europium doped hydroxyapatite (HA:Eu)
synthesized by hydrothermal method and sintered by Spark Plasma Sintering
(SPS) technique. The powders obtained were characterized by means of
infrared spectroscopy, X-ray diffraction, scanning electron microscopy, Raman
spectroscopy and luminescence spectroscopy. The HA and HA:Eu samples were
sintered using SPS technique at 900 and 1200 °C. It has been determined that
HA and HA:Eu powders crystallized in hexagonal phase, which is stable until
900°C; furthermore, it has been demonstrated that the presence of Eu 3+ ions
tends stabilize the hexagonal phase of hydroxyapatite. undoped
hydroxyapatite sintered at 1200 °C reveals a significant amount of tricalcium
phosphate (β-TCP) as a result of its decomposition. By increasing the heat
treatment temperature, different emission lines ( 5 D0- 7 F0, 5 D0- 7 F1 and 5 D0- 7 F2
transitions) were obtained due to calcium site substitution by europium ion in
the HA structure.
