摘要：

The Eu3+ time-resolved luminescence in the strontium hydroxyapatite Sr-10(PO4)(6)(OH)(2) Prepared by solid-state reaction is studied at 20 K. The emission mainly arises from the D-5(0) level. The study is focused on the distribution of sites which exhibit unusual spectroscopic features as in other apatites due to an Eu-O privileged bonding with Eu3+ located in (6h) positions. Non-selective UV excitation and the site-selective-laser excitation in the D-5(0) and D-5(1) levels were performed. Luminescence decay profiles of the D-5(0)-europium sites were recorded.
