We have demonstrated that Eu3q luminescence can be successfully employed as a local probe to explore the microscopic symmetry of the cationic sites in the Sr 2q-substituted lanthanum cuprate superconductors. It has been found that Sr 2q substitution in La1yxSrxCuO4 x;0.4. does not alter the microscopic symmetry of the cationic sites.. Further, using electron paramagnetic resonance spectroscopy we have demonstrated that the hole centers arising out of Sr2q substitution are localized around Cu2q sites.
