Synthesis of CdCO3 in situ-doped-Pb2+ grown by chemical bath

Growth of doped CdCO3-Pb2+ thin films was carried out by chemical bath. Changes of the level doping affect the structure and morphology. XRD peaks of CdCO3 sample show rhombohedral crystalline structure. A-10 and A-20 doped films exhibit peaks that indicate co-existence of one solid solution of CdCO3-PbCO3Pb(OH)2 which has rhombohedral crystalline and tetragonal phase respectively, and A-30 film indicate co-existence of CdS-Pb3O2(SO4)(OH)2-Pb4(CO2)3(SO4)(OH)2 compounds. FTIR spectra displayed the peaks at 1400, 850, 718cm-1, which are characteristic vibration bands of ion and also exhibit an absorption band at 670cm-1, which is characteristic of Pb-O stretching mode.
