Abstract
This work describes the growth of Bi2-xPbxSr2Can-1CunO2n+4 thin films by
the dip-coating technique for 0.4 less than or equal to x less than or
equal to 1. X-ray and Raman spectroscopic techniques were carried out in
order to characterize the films at room temperature. From X-ray data it
is observed that the films are multi-phased presenting phases 2201, 2212
and 2223 along with the undesirable Ca2PbO4 phase. It is also observed
that phase 2212 becomes dominant when Pb content increases. The Raman
modes observed agree with the overall features expected for these
compounds. (C) 2003 Elsevier Science B.V. All rights reserved.
