Highly c-axis orientated YBa2Cu3O7–x films were prepared on LaAlO3 single crystal substrates via metal–organic deposition using trifluoroacetates using ethanol as solvent instead of the toxic methanol. The onset transition temperature is 91 K and the critical current density under self field is over 1 MA/cm2 at 77 K, which indicates ethanol can be used as solvent for high-quality YBCO films using TFA–MOD.
