摘要：

Conductive cadmium stannate (Cd2SnO4,) films Were grown by a simple spray-pyrolysis technique using aerosols ultrasonically generated from solutions containing Cd(thd)(2)(TMEDA) and (Bu2Sn)-Bu-n(AcA)(2), and monoglyme as solvent (thd = 2,2,6,6-tetramethyl-3,5-heptanedionate, TMEDA = N,N,N',N'-tetramethylethylenediamine, AcAc = acethylacetonate). The overall film growing procedure was carried out at or below 400 degrees C thus allowing low-melting temperature materials like glass to be used as film substrates. Typical resistivity values of Cd2SnO4 films were found to be similar to 2(.)10(-3) Omega cm. The films exhibit excellent electrochemical activity with comparable or higher electron transfer rates than cadmium stannate films obtained via sol-gel methods at high annealing temperature.
