Abstract
Herein, a homogeneous Gd2O2S:Eu3+ hollow spheres with pure phase structure were synthesized successfully through the
calcination and reduction of the precursors prepared by hydrothermal method. It’s worth noting that the non-template method
is used to replace the traditional template method in this paper. The optimum calcination temperature of the precursor is
800 oC. FE-SEM and TEM observation indicate the target products are hollow spheres with a size range of 200-400
nm. When the doping concentration of Eu3+ is 7.50%, the luminescence intensity is the highest and its CIE
coordinate fluorescence lifetime are (0.629, 0.370) and 1.114 μs.
