【 摘 要 】

Bi2Sr2CaCu2O8thin films have been deposited on MgO single crystal substrates by spin-coating a solution based on 2-ethylhexanoate precursors dissolved in xylene. Pyrolysis takes place between 200°C and 450°C and is accompanied by the release of 2-ethylhexanoic acid, CO2and H2O vapour. Highly c-axis oriented Bi2Sr2CaCu2O8as well as Er- or Ho-doped Bi2Sr2(Ca,Ln)Cu2O8(Ln Er, Ho) films were obtained after heat treatment at 840°C in air.
