Abstract

A series of hydroxyapatite (HAP) materials doped with different content of europium (Eu

) were synthesized by one-pot wet-chemical precipitation method. They were calcined under different temperature. The structure

composition and luminescent property were characterized. XRD patterns and IR adsorption peaks showed the characteristic structure and corresponding groups for Eu doped HAP samples. The typical emission peaks attributed to Eu ions were observed in emission spectra of HAP:

Eu samples under 394 nm excitation. The luminescent intensity of Eu doped samples was enhanced firstly and then decreased after 500 ℃ calcination. Meanwhile

the fluorescent lifetime of doped samples increases with the temperature. Furthermore

the ratio of intensity between 618 nm and 595 nm corresponding to electric-dipole and magnetic-dipole transition (I

) increases firstly and then decreases at 600 ℃

which revealed that the proportion of substitute type and site of Ca ions by Eu ions were helpful to realize the substitute process and functional structure design.
