Research Abstract

Eu-doped CsBa2I5 with high light yield, Eu-doped SrI2 with high energy resolution, Tl and Bi co-doped CsI with low afterglow were developed by the present project. In addition. a fast luminescence was observed in Cs2ZnCl4. As a result, I published around ten ISI papers and gave around ten conference presentations throughout the present project.
