Abstract

A spray pyrolysis route to superconducting Pb-, Sr-, and Ag-substituted Tl-Ba-Ca-Cu-O thick films has been developed. First, a precursor powder with the stoichiometry Pb0.46Ba0.40Sr1.52Ca1.86Cu3.00Ox(Ag0.37) (PBSCCO) was synthesized with the particle size of this powder being subsequently reduced to 4-6 jim using a ball mill. Next, this powder was mixed with ethyl cellulose binder and sprayed with an airbrush using an N2 carrier gas. Flexible polycrystalline Y2O3:ZrCO2 (YSZ) as well as single-crystal MgO, SrTiO3, NdGaCO3, and LaAlO3 substrates were mounted on a hot plate with typical growth temperatures of 80-100 °C. Growth times of ~10 min provided films which were 5-20 µm in thickness. After an intermediate O2 anneal to remove the organic binder, these films were subjected to a flowing 2-zone thallination process. Very well c-axis oriented Tlo.70Pb0.36Bao.39Sr1.58Ca1.98Cu3Ox (TP-1223) phase material was obtained for films grown on single-crystal LaAlCO3. Films grown on all other substrates surveyed in the study gave rise to impurity phase formation and/or incomplete reaction. The PBSCCO and TP-1223 films were characterized by 0/20 and ω-rocking curve X-ray diffraction (XRD) analyses, scanning electron microscopy (SEM), variable temperature magnetic measurement, and inductively coupled plasma atomic emission spectroscopy (ICPAES).
