Spectroscopic investigation of nanocrystalline Gd2O3S for low dose X-Ray imaging applications
Dinesh Sivalingama
Recent research in the field of phosphors and scintillators for radiation detectors for medical, industrial and scientific imaging and further development and exploitation of powerful X-ray sources such as e.g. synchrotron radiation. Thus, an intense research and development continues to explore new phosphor and scintillation materials or the optimization of the current ones taking advantage of new technological methods for their preparation. Nanocrystalline Gd2O3S scintillator with structures were successfully synthesized through precipitation process and subsequent calcination for X-ray imaging detectors. In this work, a simple precipitation process was carried out using diethanolamine as a precipitant to prepare nanocrystalline Er doped Gd2O3. Scintillation properties such as luminescent spectra, light intensity and decay time were measured for the synthesized powder. The sample calcined at 400 - 900oC showed the highest light intensity. The scintillator emitted a strong red light at near 610 nm under photo and X-Ray luminescence for its potential X-Ray imaging detector applications.
