【 摘 要 】

A series of Eu3+substituted hydroxyapatite (HA) were prepared by co-precipitation reactions. The phase, fluorescence and temperature dependent luminescence of the phosphors were investigated by X-ray diffraction (XRD) and photoluminescence (PL). It is found that the doped Eu3+ions have entered the hexagonal lattice with no obvious secondary phase were detected by XRD. The5D0→7F0transition was clearly split into two even at room temperature. The predominate 573 nm peak illustrates Eu3+ions occupy more Ca(II) sites. The temperature dependent luminescent results show HA:xEu might be applied as one potential optical thermometry material.
