摘要：

A new Eu/Tb-codoped inorganic apatite Ca-5(PO4)(3)F luminescent thermometer has been targeted. Under ultraviolet irradiation, the Ca-5(PO4)(3)F: Tb3+/Eu3+ samples exhibit a blue-light emission of the host matrix which might originate from the CO2- radical-related defect produced by Cit(3-) groups, as well as the typical green emission band of the Tb3+ ions, and a red-light emission of Eu3+. These lanthanide-based thermometers (Ca-5(PO4)(3)F:Tb3+/Eu3+) exhibit different sensitivities ranging from different temperatures based on two emissions of Tb3+ at 548 nm and Eu3+ at 621 nm. The temperature-dependent luminescent intensity ratios I-Tb/I-Eu, can be optimized by the controlled relatively doping of different amounts of Tb3+ and Eu3+ ions.
