Abstract
This work describes the growth of Bi 2− x Pb x Sr 2Ca n−1 Cu n O 2 n+4 thin films by the dip-coating technique for 0.4⩽ x⩽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 Ca 2PbO 4 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.
