摘要：

A series of Gd2（1-x-y）ZnTiO6∶xBi3+，yEu3+ phosphors with dual emission centers were prepared by high-temperature solid phase method. The structure，luminescence properties and temperature sensing characteristics of the material were systematically studied by X-ray diffraction，scanning electron microscopy，fluorescence spectroscopy，lifetime decay curve and variable temperature emission spectroscopy，respectively. In Gd2ZnTiO6∶Bi3+，Eu3+ phosphor，Bi3+ and Eu3+ ions occupy Gd3+ ion position. Under UV excitation，the excitation spectra of Eu3+ and emission spectra of Bi3+ overlap，indicating that there may be energy transfer from Bi3+ to Eu3+ . The fluorescence intensity ratio technique was used to explore the different temperature response characteristics of Bi3+ blue light emission and Eu3+ red light emission. In the temperature range of 293-473 K，the maximum relative temperature sensitivity of Gd2ZnTiO6∶Bi3+，Eu3+ phosphors was 1. 133%·K-1，and the maximum absolute sensitivity value was 0. 73%·K-1 ，respectively. Therefore，Gd2ZnTiO6∶Bi3+，Eu3+ phosphor is a potential non-contact optical temperature measurement material. © 2023 Chines Academy of Sciences. All rights reserved.
