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.

Active accounts were imported to the new platform and assigned a random password by default. In order to access your account you need to access the login page and go through the Lost Password dialog (involves the system sending you an email with instructions) in order to reset your password. This step is necessary as passwords are kept in hashed form and the new platform uses modern hashing algorithms incompatible with the previous ones.
