Gd2O3:Eu scintillators with nano-crystalline structures were successfully synthesized through a precipitation method and subsequent calcination treatment as a converter for X-ray imaging detectors. In this work, a simple precipitation process was carried out using diethanolamine (DEA) as a precipitant to prepare nano-crystalline Eu-doped Gd2O3 powders. Scintillation properties such as luminescent spectra, light intensity and decay time were measured by varying the calcination temperature in heattreatment of the synthesized powder. The sample prepared at 1200 1C calcination temperature showed the highest light intensity. And the scintillator emitted a strong red light at near 611nm under photoand X-ray luminescence for its potential X-ray imaging detector applications.
