摘要：

This work describes the relation between crystallite size and scintillation properties of Eu3+-doped yttrium oxide. Nanocrystalline Y2O3:Eu3+ 1.0 mol% powders were prepared by Pechini method and thermal treated at 700-1100 degrees C. The thermal treatment temperature has influence on the crystallite sizes of Y2O3:Eu3+ nanocrystals and, consequently, on the structural and electronic defects concentration, which contributes to non-radiative recombination routes in scintillation materials. This relationship between the crystallite sizes and scintillation properties was investigated by X-ray diffraction and X-ray excited optical luminescence measurements.
