USE OF A SINGLE-SOURCE MIXED-METAL PRECURSOR FOR THE PHOTODEPOSITION OF Pd/Ni OXIDES THIN FILMS

irradiation of thin films of a polyketonate pd/ni heteronuclear complex, pdni(dba)2 [dba = dibenzoylacetone)], produced uniform films containing pd and ni as shown by edax analysis. the x-ray powder diffraction spectrum showed peaks associated with elemental pd and nio. the morphology of the films was examined by sem measurements showing a uniform granular surface with particle sizes of 100 nm or less. the xps results show that the ratio of pd/ni (1:17) present in the film does reflect the stoichiometry in the starting complex. the large amount of carbon (52 %) detected on the surface of the film may be due to the presence of phenyl rings in the precursor complex.
