Abstract

YBa2Cu3O7−x (YBCO) superconducting thin films are synthesized through non-fluorine sol–gel aqueous processes. Diethanolamine (DEA) and triethonalamine (TEA), which have similar molecular structures but different complexation abilities and molecular weights, are separately used as chelating agents. Compare to DEA, the precursor with TEA additive exhibits higher stability and yields films of superior microstructure and surface morphology. Finally, the YBCO film produced from the TEA precursor displays a sharp superconducting transition, with a J c of 1.7 MA/cm2 estimated at 77 K in self field.
