Abstract
The phase formation of the samples with the norminal composition (Y1-xCex)Ba2Cu3O7-δ(x = 0,0.05,0.1, 0.3, 0.55,1.0)has been studied by Raman spectroscopy. It is found that the impurity phases of BaCeO3 and BaCuO2 have been formed with Ce doping, besides the orthorhombic Y-123 phase. The results suggest that Ce element may not substitute for Y element to form a Ce-123 phase. Moreover, Ce element formed an impurity phase BaCeO3 with Ba.
