Gd2O3 nano-powders doped with Er3+ and Yb3+ were synthesized using the combustion method. X-ray diffraction and the scanning electron microscope techniques were used to estimate the crystalline sizes and the morphologies of the materials. The Scherer and the Warren Averbach calculations were employed to estimate mean crystalline sizes and size distributions of the powders. The crystalline sizes were found to be
