Abstract
β-Dicalcium silicate (β-Ca2SiO4) doped with Eu3+ was synthesized by sol–gel method. The luminescence intensity of the mineralization products formed during the hydroxyapatite (Ca10(PO4)6(OH)2, HA) conversion of Eu3+-doped β-Ca2SiO4, in 0.25 M K2HPO4 solution, were detected using luminescence spectroscopy. The results indicated that the luminescence intensity of Eu3+ ion gradually depressed with prolonged mineralization time, and it could hardly be detected with the complete transformation from β-Ca2SiO4:Eu3+ to hydroxyapatite. The change of Eu3+ ionic concentrations in the mineralization products and the final solutions after conversion reaction, were further examined using
energy-dispersive X-ray and inductively-coupled plasma mass spectrometry, respectively. This suggested that the process of mineralization can be monitored with the luminescence intensity of Eu3+ ions in the mineralization
products. The current study will open up a new and simple in vivo avenue for in situ monitoring hydroxyapatite conversion with a fiber luminescence spectrometer.
